Oneirosis - a disordered state of dreaming

View File

---

A series of mechanical frameworks based around sleeping/dreaming/etc.
 

Dreaming
In the elder scrolls, when mortals sleep their minds actually wander through the realm called the dreamsleeve. Sleeping with high alteration skill and/or active alteration buffs from alchemy/enchanting etc. can result in a lucid dream, which restores Ego. Assorted conditions and situations will interfere with dreaming, resulting in a range of nightmares.

Parasitic Hypnagogia
You are not the only thing in the Dreamsleeve, dream too far from reality and you might find something horrible and incomprehensible. Lucid dreaming too regularly without a sufficiently high illusion skill and/or illusion buffs to protect yourself might result in...SOMETHING happening causing de/buffs to spellcasting, new alteration spells and the ability to immersively reload to your most recent (non-disrupted) dream on death. The magnitude of these de/buffs and number of spells increases as your Ego drops, but if it drops too low you will get a game-over. Can be cured if something else gets a tighter grip of your soul. SHOULD be compatible with mods like defeat that prevent death, or mods like player death aftermath that "detour" death using the ondying() event, but no guarantees that it will work with anything. 

Oneirosiphoning
If Vaermina can steal dreams, why not you? Complete 2 short quests for a new NPC in the ragged flagon to unlock the ability to project yourself into other's (wet) dreams to drain their energy to raise your magicka. Oneirosiphoning any form of oneirotic target is not recommended. This IS fully compatible with other succubus mods, so you can slap it on top of your favourite to expand your experience with the original classical succubus trope.

Urges
Everyone gets cravings and urges, with those urges getting darker and more insistent for those with a weak ego who struggle to integrate their shadow. Adds a constant minor quest that requires the player to increment specific game stats, as a means to provide impetus for varied roleplay and gameplay. The lower your ego, the more likely it will require a crime stat. Failure to do so results in a slow ego decline (though never to 0) while fulfilling them by incrementing the stats high enough results in a moderate ego boost.

Vaermina Experimentation
The cultists in Nightcaller Temple were not sitting idly by, while most was lost in the Orc raid some remains. 3 new spells (to detect sleepers, to invoke the skull of corruption effect via magicka instead of enchanting charge, dream on command) and  Nightmarish rings that function as limited capacity skull of corruptions to complement them.

Solstheim Sleepwalking
While your body is mindlessly working on Miraak's great works, the Reavers of Solstheim are more than happy to take advantage. Get raped while sleepwalking on solstheim, with a variety of soft-integrated consequences ranging from sexlab stats to apropos wear and tear to hentai pregnancy impregnation etc. etc. Does essentially the same thing as the similar feature in dealing with sexual daedra, but more polished, so there is a patch in the downloads that buries DwSD's version behind a condition that oneirosis isn't installed. Be aware that this required overriding the vanilla DLC2PillarScript script. Great care was taken to ensure all changes are soft-integrated, so even if the script is orphaned by disabling the Oneirosis esp it SHOULD still work fine PROVIDED that SKSE is still installed, but delete the loose script if something goes wrong so that it will default back to the original inside the dragonborn bsa.

Skaal Amulet
Frea's amulet protects her from all Miraak's influence over the dreams of the island's residents, some of the ancient skaal in their icy tombs were buried with similar amulets. Has an assortment of effects, both protective and restrictive, on almost all aspects of the mod while worn.

 

Cutscenes
Adds cutscenes to all dreams and oneirosiphoning events. Female character only.

Main Menu Replacer (optional, standalone)
Replacer for the main menu image with pov of being oneirosiphoned and the music replaced with a ~7min30 ASMR/JOI, both in the style used for the ingame oneirosiphon feeding events. Comes packed with alternate images A) using the player dream-self colours and B) a more conventional "demonic" succubus.

Loadscreen Replacer (optional, standalone)
84 loadscreens of other Hypnagogia victims who have met their ultimate unfortunate Ego-death end, with 42 pairs of loadscreen tooltips for all the oneirosis mechanics and lore. Tooltips:

Spoiler

Some of the Ehlnofey sought survival in forms far more abstract than biology
Ideas, intentions, habits and other abstract patterns of thought can shape the Dreamsleeve just as tools can shape the waking world. Symbolism, self-image and expectations can have major consequences
It takes a great and constant force of will to maintain an independent sense of self (Ego) while adrift in the Dreamsleeve, let alone when being actively pulled deep
A mind with its will and Ego stripped of it, like this one, is a valuable vessel for an ill intentioned force to "breed" thoughts, ideas, perceptions and other constructs of the mind with
The barrier between the dreamsleeve and the waking world is thinner than you think. A mind losing grip with reality can find their dreams affecting the world and the world affecting their dreams
Many things can happen when your mind drifts into dream. Not all of them pleasant
Sleeping with a high Alteration skill and/or active Alteration power modifiers like potions can result in a lucid dream
Illusion and/or Alteration power modifiers only need to be active when you first fall asleep to affect your dreams
Elgrim has been selling potions to help the less fortunate residents of Riften reach the escapism of lucid dreaming
Lucidity while dreaming can allow your mind to travel far from the anchor of the material world into the more chaotic and ephemeral areas of the Dreamsleeve, dangerously far
Having a lucid dream while sufficiently aroused can allow you to reach a nocturnal emission
Foolish mortals whose souls are claimed by the daedra will visit their patron's realm instead of the dreamsleeve each night, and upon death
The ancient skaal had lost techniques for creating protective amulets which protected the wearer's mind from the dangers of dreaming
An ancient evil force is influencing the inhabitants of Solstheim through suggestions in their dreams, a threat last seen from Dagoth Ur
The bandits and reavers of Solstheim will happily take advantage of any attractive hapless sleepwalkers
Rumors say that a heretic of Vaermina's cult fled to the Thieves Guild in Riften and has been stealing residents' dreams along with their septims
The powerful symbolism of sexual intercourse, specifically the release of life force at its conclusion, is a simple and effective means to Oneirosiphon power from dreaming men
Oneirosiphoning is disruptive enough that it can only be done once a night
Males will need a decent time to recharge their energies after being oneirosiphoned, but teasing and denial can make that faster
Attempting to oneirosiphon women will not yield any measurable effects, but it can still be fun
Attempting to oneirosiphon a target suffering any form of Oneirosis, such as Vampires, is unlikely to end well
Stolen dreams may empower you in the short term, but the withdrawal will be unpleasant
Vaermina covets and hoards dreams for the potent magical potential they hold, but despite her best efforts she does not have a monopoly on them
Legends say the Nightcaller Temple overlooking Dawnstar was the site of evil experiments into new means of manipulating dreams and nightmares
Nightmarish rings are a passably successful attempt to replicate the abilities of the Skull of Corruption
Not all the evil spell texts were destroyed in the fire that ravaged the Nightcaller Temple library
Beware lucid dreaming without a high Illusion skill and/or active Illusion power modifiers like potions, you are not the only thing in the Dreamsleeve
Some people wake from dreams containing particularly powerful inspirations to find they understand much of the deeper truths of reality and magic
Some people wake from dreams containing particularly horrific revelations to find their mind assaulted by alien thoughts, doubts, impulses and perspectives
Time and causality are more flexible in the Dreamsleeve. Lingering prophetic glimpses, or perhaps fragments of collapsed once-possible futures, can sometimes be grasped upon waking
While at times frustratingly limiting, the physical body serves a critical role in providing stasis and stability to the infinite chaotic raw potential of an unbound soul
When the body dies the soul is cast into the Dreamsleeve with no achor, to drift until it forgets all it was and eventually finds a new host. Assuming it isn't snared by a daedra or other such fate
An unbound soul with sufficient familiarity of navigating the Dreamsleeve, a strong enough Ego and a great deal of luck could potentially find their way back to their own body from when they last dreamed
Self actualisation from short periods of healthy lucid dreaming or through satisfaction of certain urges can help reinforce a faltering Ego
Urges will not subside they are satisfied, only grow more insistent. Repression is not a long term solution
The more fragile a person's Ego, the more likely their Urges will be maladaptive instead of healthy
Take care when Oneirosiphoning, it takes some time and if you are detected it will be viewed as an assault
Nightmares are as damaging for the Ego as a lucid dream is nourishing, with both dependent on sleep duration
Having the emotional and psychological maturity of a high Ego will make you more likable, while the opposite is true for those with low ego
Poor self actualisation from unmet urges and invasive Daedric nightmares will shatter your Ego
Even the most poorly maintained Ego will never decay to Ego-death, unless affected by certain outside forces
The nightmares in Dawnstar affect locals, but not travellers. Best not to stay too many nights in a row

• Category
  Adult Mods
• Requirements
  SKSE
• Regular Edition Compatible
  Yes
• Install Instructions

  Which files to use
  The _main file and the offsite mega link are mandatory, the loadscreen and menu replacer files are optional and/or standalone, the patch is for dealing with sexual daedra.

  
  Requirements
  The only hard requirement is SKSE. Major soft-integration with sexlab aroused (especially when also used with devious devices) as both Oneriosiphoning and Lucid Dreaming can trigger hands-free orgasms. Has an alternate perspective start, with its own soft integration with sexlab to pre-generate sex diary stats based on starting choices and slavetats/dd for certain choices. Provides a means to trigger "immortality" for dealing with backstories revived. Assorted much lesser soft-integration, mostly during the sleepwalking event or when casting "derealise" spell.

  
  "Can you add soft-integration for [framework variant] or [mod]?"
  Give me the relevant script fragment that will do it in a soft-dependent manner and I will slot it into the right place (without testing), otherwise the answer is no.

  
  Note on cutscenes
  This mod makes extensive use of the neglected red-headed stepchild that is the playbink() function. Bethesda barely got it working in the first place (eg. trying to take a steam screenshot of a cutscene will cause skyrim to freeze) and basically gave this function no support across some versions, especially VR. Before you dig into the mod you may want to console yourself the "onedebugcut" spell and run the "quicktest" option.

  
  Note on LE/SE
  I deliberately used the old LE nifscope and ext1 dds formats along with form43 on the esp (no form44 relevant forms were used inside it) so that it is natively compatible with both versions out of the box.

Wow! This is one of the most interesting concepts I've come across in quite a while! I'd love to give this a shot! Since (if I'm understanding correctly) this is still somewhat in beta, is it relatively safe to uninstall in case something in my load order doesn't play nice with it? The impression I get is that this mod's lack of dependencies means it shouldn't be an issue... but as someone who isn't a mod author/creator, I think it's always best to ask. 😆

Cannot wait to try this with Ostim. Sounds like lots of fun. 

Congrats on the release!

[Cannaisseur]

This is definitely one of the most interesting and ambitious concepts for a mod I've seen in awhile.  How well would this work with a straight dominant male PC? It seems like its definitely intended more for a female PC.

that "Urge" concept looks really interesting!

You will want to use the "onedebug" spell to "curhyp" and wait long enough for any oneirosiphon de/buffs to decay but otherwise it should be pretty safe

Mechanically it will work, but I only bothered to generate female cutscenes. Would work great as a roleplay prelude to using one of the sex-change mods, but for a STRICTLY straight male you will want to delete all the related cutscene files (as the script will simply skip over playbink() calls if the file is missing), though it would be a pretty anaemic experience with no cutscenes.

This one is going to be interesting.

Im mostly interested in the oneirosiphoning.  Would it still work on female NPCs?

To quote loadscreens one_load39/40: "Attempting to oneirosiphon women will not yield any measurable effects, but it can still be fun"

Yeah this looks fascinating. I'll definitely follow how this turns out.

 

Congratulations on the release (ahem)

[Lasaubia]

This looks so cool, even from a non-lewd perspective! Now I'm excited to roll back another Vaermina/dreams oriented character. This really seems like it could do a lot in that aspect!

An amazing release worthy of a permanent place in any modlist!

Tried out the mod, and the main features function well on my end. I'm impressed by how compatible the mod is with everything. Can't wait to see what comes next!

 

The art and sounds are already top notch, so any improvements will surely be completely mind-blowing. The cutscenes function utilization for dreams is genius. Just the fact that the restless sleep for werewolves and vampires is more tangible now makes the mod worthwhile.

 

As for ideas and suggestions, some of the daedric lord sounds are a little quiet compared to the dreamer sounds. In addition, some of the walk-cutscenes that are interrupted feel a bit abrupt, though that may be as intended. For example, the nightmares caused by Vaermina or the ones in Dawnstar could be longer.

 

Personally, I would love to see even further daedric expansion, such as Sanguine and Sheogorath, now that the framework is established. They seem like the kinds of Daedric lords to cause "interesting" dreams.

I suppose some Aedric dreams or vanilla quest-related dreams might be interesting as well. For example, Dibella could grant adult dreams and Akatosh might gently remind a dragonborn player about the main quest. Maybe the dawnguard quest being active could lead to prophetic dreams about the sun being blocked, or the mages college quest could cause dreams featuring the Psijic order and the eye of Magnus.

The framework is genuinely so good that I could see the mod increase in size many times over if additional non-adult dreams were to be integrated. Thank you for sharing this mod!

 

 

[poporaltemporal]

Its probably me just personally so dont get this too offensive way. I watch the screenshots and checked the files and red some of the description and there seems to be really nice features in the mod. However I am bit confused about the mod name. Why use greek mytology when you have skyrim mytology? Its pretty extensive work that you did on all the art and the water painting style style looks really good but I cant really get over the anime style. Personally would like to give this mod ago but the anime stuff and the greek references really give me the creeps.

just merge the new 2mb file or redownload the big 1.6 giga as well?

[shelloil]

Just installed the latest version and found the player does not move after waking up, put the old version back and player controls work fine on wake up

[Shiana01]

I have the same problem. I installed the latest version. 
After waking from sleep, I can't move or do anything. 
The old version works without any issues.

So I'm playing on the LE, and despite the game loading and my load order showing the mod as present, nothing happens. I've installed both the latest version and the required file from Mega. I don't know what's going on.

Sounds like the scripts aren't running. Console yourself the "onedebug" spell and try "quicktest" or "givsuc" to see what happens

[qalavix]

Just a quick thanks for making the loading screens separate; far too few modders do this, and i really appreciate this tiny detail!
