Both of those. I did manage to hallucinate becoming a doggo but I couldn't move myself much at all because of the paralysis and if I tried to move too much I'd wake up. Sometimes nightmare things would appear but that comes with the territory I guess.>>35212221
Essentially, a self-enforced hallucination of a seperate creature or person or thing. Think of force ghosts from Star Wars, only you have to construct them yourself through meditation.
