I used to do a tons of designer drugs to deal with a death in my life and I would do them on a nightly basis. Go to work at 7, come back at 3, eat dinner, workout, and then get fucked at 6 till I went to sleep at 3 in the morning and do the whole routine over. I would do this like 5 days a week and it was all fine until I started getting drug indused psychosis during work when I was not even high. It would mostly be shadow people at first or stuff moving at the peripherals of my vision but it eventually got to where I would see people who died, which is why I kept doing it so often. I would also see beings around the place and I hear stuff. All these later still kinda convinced there is an alternative dimension living congruently with ours but we just can't see it.

The scariest thing I saw during that time was the ceiling was made out of dead bodies and heads would pop out of it to talk to me.

I eventually stopped doing those drugs after I tried to cut my female friends hand off and I think I wanted to split her throat but the memory gets blurry
