Ive tripped off weed before, like hearing music or my phone ring when im really stoned, Ive smoked weed laced with angel dust a few times, its pretty good I got tunnel vision the first time I smoked it and thought some random person at a bus stop was talking to me, so i just had to say "sorry? I never heard you" then the woman said "I never said anything" then i just looked away and got into a daydreamy trance and when i looked back she wasnt there...
