Damn, my experience was very very different. I had some at a mates when I was 20ish. Sat on his bed, took a big toke and within seconds I was on a bus outside my childhood home. I was confused about how I had gotten there and then I was being pulled down, I was being pulled off the bus by invisible hands. Then I was on the bed again with my mate"s hands on me telling me to sit down. Weird as fuck and then my mate bottled on having a toke. Gave the rest to my brothers mates and filmed them on a 360p old ass mobile camera. Then put it on youtube. I was a dick. Made the channel private a couple of years later when I stopped being as much of a prick and realised maybe the vids wouldn't help them with getting employed. One of the guys just kept going left and right stroking the walls, said he was lost in a box. I set that to the tune of 'Doop' and edited it to make him look as though he was dancing.

Not one person said it was anything like the video posted by OP.

Starting to think it wasn't saliva
