similar for me but w legal drugs. my doctor switched my anti-anxiety/depression meds and the interaction made me think that i was talking to god and that i was going to die.
i called 911 and the cops showed up about 3 hours or so later. my mind was clearer when they did and i tried walking up to them to tell them that they weren't needed, but they put their hands on their guns and yelled at me to stay away because i was "being aggressive". i just stood there on the sidewalk and watched them look for me for about a half hour until i got hungry and walked away.
