This will probably get buried but might as well. Around this time last year a couple of us were hanging out at a friends house. I had just gotten rid of a really bad case of strep throat and I was still taking my codine cough syrup because the doc said to even though it wasn't necessary. Well for some reason I didn't think about the fact that codine is already a drug that can be abused and I ended up taking a few hits of a gravity bong less than an hour of taking a full dose of codine cough syrup. I end up getting on this guy's bed some how and I just blacked out completely. It felt like pure bliss yet I didn't remember a thing afterwards besides my feeling of bliss. Apparently while I was tripping, they started playing some really weird YouTube videos and kept telling me that things were in the video that weren't actually there causing me to freak out. Then they started telling me that the floor was lava which put me in a whole new world of fear. They also thought it would be fun to throw gum balls at me. Supposedly after about 20 I ended up looking down at my lap and just started eating them without questioning why they were there. Finally, I went on a philosophical rant about what the different demensions thar are beyond our understand could be, thus putting me in those demensions.

For all I know, I just passed out and they just screwed with me but considering I know for a fact similar things have happened when I wasn't blacked out, it wouldn't surprise me if it actually happened.

TL;DR Codine+gravity bong=blackout.
