Actually a story of my own kinda similar to this, I believe one of my friend tried to kill me when we took LSD.

It was my 7th or so trip and I had this friend named B, B is a kinda quiet guy, keeps to himself mostly, but seemed normal enough.

We were at his house just him and I and B smokes a couple fat bowls before the comeup of his trip, we had each taken 4 tabs which was pretty crazy and I didn't even smoke any.

B started to get weird, he started pacing around the house, wide eyed and not saying anything at all.

I kept asking him if he was okay and he'd go from being totally weird batshit crazy to super happy saying "Oh yeah!"

I was tempted to call 9-1-1, he was acting fucked up and I thought he was overdosing (being high I thought we took nBOME)

Then all the fucking sudden he starts punching me in the face, he got two clean shots on me, one in the lip and another in the nose, I start blocking and when he fucking stops attacking me I get up grab my wallet, car keys and smokes and tell him "you're fucked up man" and trying to leave his room, he gets me in a choke hold and literally starts strangling me. I go into fight mode and grab his arm and pry it off my neck, then clench his arm and swing him over my shoulder and slam him onto the floor as hard as I possibly could.

I run into his siters room and tell her he's trying to kill me, she suggests I hop out the window but I can't because theres a screen.

Suddenly at the door is B, I had my whole body against the door and he was pushing it and it was about to fucking snap in half, the bottom of the door was at a thirty degree angle.

Eventually I hear B walk away I book it out of his sisters room and get the fuck out of there as quick as humanly possible.

I believe he has fucked up issues he has been bottling up, I believe he is probably going to do fucked up shit in the future, and I am glad I wasn't his first victim.
