Well once I got so high (only smoked like a .6 in a joint and two bowls) and it was when I first started smoking, that at one point I just kept passing out and waking up, passing out and waking up, literally like that. So I decided fuck this I'm gonna lie down in bed but not totally like I'm going to sleep just lie down to catch a breather. What happens....I pass out again, only this time to be overcome by an incredibly intense feeling of falling down stairs, a very long flight of stairs, and of eventually banging my skull on the floor as hard as a fucking iron weight. Not only did it feel like that but at that very moment I heard a very loud "boom" in my head which caused me to get up immediately, literally terrified for my life, and proceed to puke my guts out (I'm good with that though as I had my garbage handy). Emptying the garbage so that my mom wouldn't know I even threw up in such a ridiculous quantity in another story though. Quite a disaster that was.
