There are two stats that can affect "dreams" -- dream chance and nightmare chance. I'll be notating these by dreamChance/nightmareChance below.
Initially, these start at 0/6, but with the Enlightened class (unlocked by dying once and starting a new game from there), these are 16/4 (adjusted for starting Cosmic Insanity). The dreamcatcher applies 0/-30, and the dreamstone applies +20/0. Assuming you've bought both of these, these should be 20/-24 or 30/-34 as Enlightened.
For each Cosmic Insanity (the eye) you have, you gain +3/+4 to these numbers (and lose the same if it is negative). You can gain Cosmic Insanity by reading about the order's past in the library (+1); having your first nightmare (+1); in the Maze nighmare, wandering randomly twice, following the pull, and refusing to take the cube twice (+1); using the effigy you receive from Vael in exchange for the 682 sample to gain additional Cosmic Insanity on making a new character (+2); starting as Englightened (+2, mentioned above already); using an elixir of exertion (+1, 1 day only); or wearing pendant you can buy from Vael (+1).
Dreams are the last thing the game checks for happening on any given night. Finding Yuumi, Nyxa's third night, and being blessed by your patron all take priority over dreams/nightmares.
Dream and nightmare chance are capped at +50/+50. You have a dream chance% chance of getting a dream when you go to bed if one is valid, and a nightmare chance% chance of getting a nightmare. Each dream and nightmare can only happen once.
To max your dream chances, use the following step by step guide.
- Bring Vael the Feragon to unlock the 682 job.
- Bring Vael the 682 sample and get the effigy.
- Die by any means.
- Use Vael's Effigy to increase your starting Cosmic Insanity, and select the Enlightened class. Your character will start with 22/12 odds.
- Read about the order's history in the library. Odds = 25/16.
- Find ways to pass time and make money while waiting for both the base and maze nightmares. The base nightmare will ALWAYS happen first. Odds = 31/24.
- Buy the dreamstone. You can do this while waiting for the nightmares, as it won't affect your odds of getting them. After doing so, your odds should be 51(50)/24, but you'll not have any nightmares left.
Here's a list of all dreams and the ways they can become possible. I am not disclosing the contents of these dreams here, as that's for the player to find.
- Take the wolf girl home.
- Let the wild wolves take the wolf girl with them. (BUGGED -- keeping her awake will NOT add this dream)
- Impregnate the wolf girl.
- Begin the Azri contract.
- Begin Vael's Feragon contract.
- Have sex with the day fury.
- Impregnate the day fury.
- Impregnate the Wolyrn.
- Use the deer pheromones on the deer OR take her antlers OR force yourself on her while she is awake.
- Have sex with Naafiri.
- Successfully heal the wyvern.
- Tell Nyxa the truth about not killing everything and invite her on some hunts. To do this, on the third day of the Nyxa romance (the day she is depressed), talk to her and ask about what's going on. Make sure you've built up enough affection with Nyxa before this, and don't force yourself on her.
- Have no valid dreams. This is the "insect dream".
