I have schizoaffective disorder, so I've had a lot of "spiritual" experiences, some I still can't totally shake off how real they felt despite being well medicated for years.

I once met a god in my dreams. He never spoke to me, but I could sense what he wanted to say. He told me I was actually two people, one was destined to destroy the world, the other was me, who was actually the creator of the world. Apparently I was asleep and all of reality was just my dream, and this other person inside of me was destined to wake me up, ending existence as we know it.

I also had a shadow woman with glowing green eyes who would show up constantly (while I was awake this time.) I thought she was also a god, who was in love with me. That's been one of the harder ones to shake off. I met somebody who claimed to be psychic a few years ago who described the shadow woman exactly as I remembered her. He claimed she was protecting me. That was unsettling, because I'd not mentioned her to him even once.

Besides that I used to see ghosts a lot before I was on my meds. Most of those aren't very interesting though. Just a person or animal who wasn't supposed to be there and nobody else could see.
