Question for pot smokers....... please answer?

had an experience a while ago and was wondering if it was normal. i smoked and the effects were very powerful. i was very disoriented and i was very spacey. i also was blacking out and the only way i snapped out of those black outs was when my friend talked to me. it felt like i was lteraly in a dream. i also was very into my head and my thoughts none of which made sense. we wee only a couple blocks away from my house, and if it werent for my friend i would not have been able to fing my way back. eventualy we got in my house and it looked like my house but it also looked very different. i was also having auditory hallucinations. i heard the hum of the refrigerator and i was deep in my thoughts and it began to turn in to a catchy tune. but then i kind of shook my head and i realized what it was. i am also on zoloft and was wondering if any of these effects were normal. it seemed like a normal high but it seemed to be much more intesified by the zoloft. this was my first time smoking
