you know funny enough that rarely, if ever, happens. The great thing about DMT is that your mind is intact. I like to do it with about 3 friends, put on some good flowing music(tried lupe fiasco, but everytime the bass kicked in and the verse changed up my visual changed and it was a little too confusing, with good flow, it all melts together really nicely) everyone takes a hit and just lay back, sometimes I like to put a blanket over my eyes so no light gets in, you are in another world man haha.
Don't have too many people around talking, that's what can get scary because so many things are going on at once. I got freaked out once, but only once. Luckily though, you can still be rational on DMT as long as you just say hey, I got dis.
