scitzophrenia episode while smoking weed

OK i smoked weed for a bout all of last year straight green and it was going fine. Only smoked on the weekends sometimes weekday if i could handle work the next day, i stopped about November the reason why i stopped is because i think i had an episode of some sort. I don't know what it was but it shock me enough to not want to do it, i did do it 1 or 2 times after that but only a puff or 2 of a j nothing to get me high. any way the episode i had 2 big cones out of a crazy glassy that i used to own was German only had it for a couple of weeks but it got u high beyond belief. So i usually got high then had a shower then sat on my computer, well up to the shower was going awesome then i got in the bathroom i was talking to my self in my head like normally ie if ur in the shops day dreaming about stuff and you no ur doing it but ur not really concentrated on what your saying, but this time because it was dead quiet and i was high i asked my self a question and id normally id reply to my self like of course or f**k yea something ive always done just talked to my self in my head rite but this time i asked my self and i didn't have to reply because a voice in my head did then i reply back with something then its raise its voice and said it straight away vice versa getting quicker then i snapped back and was like wtf was that scared the sh*t out of me so i went back still high as a kite and sat down played wow only just got new game time haven't played in about 6 months and was just running round didnt know what i was doing cause i was screwed and all i can do is pick out how fake sh*t is when im high now if stopped playing wow to its been 4 - 6 months and its the best ive felt in over a year after that night its really sketched me out cause i thought i might have had a sign of schizophrenia but now i have got my feet back on the ground and my head straight i dont know if i over reacted but yea what are yours thoughts
