The Mental World Meme

Everyone’s got a special brain, some more special than others - they all contained a little retreat from the real world that helps gather their thoughts and memory, and keeps them from going completely over the edge… usually. But sometimes that little world that someone created in their mind has a few cracks or skeletons buried so deep inside that their waking mind doesn’t realize they exist.
Whether you came in on purpose or by accident, a mental world isn’t a place to be mucking around casually, you might end up discovering something about that person you really didn’t want to know. Or you know, end up making things worse for them... but if you're really careful, and have a knack for it, one can do a world of good - just be careful!
Rules:
1. Top-Level must put in a description of their character’s mental world. Blank Top-levels will be deleted.
2. The mental world is often an imperfect metaphor for the person: For example, an artist’s mental world is all done in garish black velvet art, with his rage at being dumped represented by a bull charging around, or a paranoid schizophrenic sees a distorted 1950s neighborhood with spies creeping all over the place. These worlds aren't empty, they're often filled with inhabitants that reflect either an aspect of the person themselves, or how they view the world outside, and you might even met the "owner" of these minds.

3. Please put a warning in the header if there’s a chance your mental world will delve into trigger-y or uncomfortable content
Prompts:
1. Whoops!: Well you didn't mean to touch that, and now you're stuck in somebody's head and now you gotta figure out how to get out of there before you touch something else and make it worse.
2. Don't worry, I'm an expert: You got the Psychonauts Merit Badge, or a Dream Therapist license, or you're the headed of a school for gifted youngsters, you got this, man. You're here to help this person out to work through whatever issues they may have, but remember, while they consciously agree to this, their subconscious might have other ideas, but helpers will be there.
3. {Inception Horn Blare}: You're here for a purpose, but not necessarily for the owner's good. They got something locked away in their brains that you need to get, or something to plant in their head - even if it's just an earworm. Of course, their mental selves will look poorly upon such intruders and react - often times quite violently, so don't get caught.
4. Basic Braining: Whether it's learning how to enter people's heads, or some other skill, you two are here to learn and train. Now remember to follow the teacher's guidelines or things could get messy!
5: You got your brains in my brains: Somehow your mental worlds merged together and is making a huge mess all over the place! Obviously you can't keep it all together, I mean who wants that in your head? There might be a way to get it unstuck, but search me.
6. Obligatory Party Time: Who needs to be all serious all the time? Sometimes you just want to relax and do something crazy that you just can't simply do in the real world, such as stomping around like a Kaiju or have a massive disco roller derby party. Stay within the limits, and have a good time. If you want to do something more - well, that's none of my business.
7. Other: Well, as they say, the only limit is your imagination.
