I'm pretty sure by definition when you are psychotic you can't tell the difference between your fantasy and reality- period. Or at least, have a difficult time in doing so. Escapism =/= delusions.

It obviously isn't a very healthy habit to get into, because the cycle of escapism ultimately leads to whatever issues you are having with the "real" world to get worse, because those problems only resolve themselves when you face them head on.

But trust me, I've been there. Not something I shared with anyone, because it was always something I was terrified to talk about irl. But I do know how real it can feel and how it really does call into question your sanity at times. I can't say you should do this-or-that because I'm not a professional and ultimately my advice could be harmful.

What helped me the most was shoving my fantasies down when they popped up in the sense that any time the thought came up that maybe this is real was pretty brutally struck down mentally. "No, that's just a fantasy [list of logical things that debunk said fantasy]" I don't know if this really helped me in the long run or was just a dangerous form of repression, but at least it the short term it made me finally let go of the fantasies and escapism that went above and beyond in the sense that they really did start to warp my perceptions and really affect my life.
