Reaction to weed

I had smoke a bit to much weed the other night, and I kind of felt like my head was shaking, and suspected I may throw up so I stood up to go to the bathroom. when I opened the door. I lost conciousness and according to my girlfriend who was there I started bouncing on my feet in a squatting position like I was falling but catching myself. This proceeded for about 5-8 seconds then I "woke up"mid bounce. without a clue of what just happened.
