I went to my friends house smoked some ganja (only 4 bowls) watched Half Baked and another movie. Then I started to bike home but as I was biking I wasn't really stoned anymore but I heard a women say "Do you hear voices in your head?" In the back of my head, while I was trying to think of what I did a couple days ago that's when I heard that voice. No one was around me and then my head started to hurt, I got a headache and my mind went blank. Couldnt think of anything. After a couple hours it went away. I feel completely normal but I don't know what to make of what happened. I KNOW I heard what I heard coming from my head. I was biking in the middle of a dead side street and heard it so clearly and loud. I tried yahoo answers and got shitty responses. Google doesn't work bc no one experienced exactly what I did. I have no where to go to find out if I'm going crazy or what please can someone explain to me maybe what happened? TL;DR Got high, started biking home, wasn't really high anymore, heard a lady voice say "Do you hear voices in your head?" in my head, head started hurting, got headache, don't know what to do worried I'm going insane Edit 1: Could I have schizophrenia? Or couldve it been a spirit? It wasn't me bc it didn't sound like my voice in my head so it wasn't me high making things up in my head, I wasn't even that high when I heard it.
