So why you're seeing 'spirits' and not 'random monsters'? Well I don't see how gasoline fume 'spirits' are any more realistic than big hairy monsters with tentacles and googly eyes. It sounds really generic, honestly. Might as well be Halloween ghosts with white bedsheets and rattling chains.
See I'm really not invested in whether what you see is real or not... However, as you said when you're on meds, the spirits don't move things around... Isn't that probably indicative of something?
I mean, it might be real, or might be not. What would you do if it were definitely real?
Do you believe in the THIRD SUMMER OF LOVE?
