Dude, you just got high. Chances are that the previous times you smoked weed you didnt get high and this was your first time. I cant believe you told your mom though

And as for passing out, it almost happened to me. I felt really light headed and fell on the sidewalk but got up after a few mins. This happened to me though because I was smoking a huge blunt and I would only breath through the lit blunt, so I dought I was getting much oxygen.

But seriously, it was just a plain bad idea to call your mom and tell her that youre high. But ya, what you described is just you getting high. When I smoke different types of weed I get different effects but I dont freak out. Like sometimes it feels like Im wearing a giant pair of shoes and that everything is extremely sensitive.
