Yes, several. I've never done drugs, I don't drink, I have no diagnosed mental disorders.
Can't really talk about it super openly here, but I would be happy to DM you. Both dark and good ones, mostly good.
The good ones were wonderful, made me feel more alive and aware than any other time in my life. Saw people healed seemingly miraculously, some other stuff that is really personal but very lovely.
The bad ones, especially the worst one was almost indescribably horrific. I'll just say I decided it would be interesting to try and contact beings that shouldn't be contacted, I was skeptical and didn't think it would actually work, and I was horribly wrong. They accepted my invitation, I wish they hadn't, terror followed.
DM me if you wanna know the details.
