That a rumor, about how those assasins used to smoke hash and they were called hashashins or w/e, and thats what the word assasin derived from. I know what you're talking about, it's definitely just a myth.

a friend and i are buying 4 hits of acid this weekend, we've had it planned for a couple weeks. it will be the first time for both of us. maybe after that, when i get high, ill be more open to hallucinations?

ive had some really slight stuff like the guy was talking about, where he thought he was seeing someone come down the stairs out of the corner of his eye. ive seen like flickers of light and stuff out of the corner of my eye, light that isnt really there.
