Marijuana..... Causes hallucinations?

Ok Ive smoked before and what not, I hadn't done it in a month my homie said it was some of the best shot he's ever smoked .... We smoked a blunt ... And like 5 min afterwards everything seemed like as if I was dreaming, I got on the bus and like there's a bright yellow pole in the back I stated at it and it felt as if I was swimming in the there like I saw nothing but that pole, I saw like a small person swimming in there it felt like as of I was in there, then I also saw my friends face like a cartoon clay face...... O.o it wasn't laced or anything , I gotti school and saw my gf we were kissing and her lips felt soo good, then she was like grabbing my dick, and I like lowkey butted I don't remember , is that notrmal!?
