Absolutely. At the end of a hotel party, a friend put down lines of “trail mix” (ketamine+coke+MDMA). But it was actually just ketamine. I’ve done my fair share, I’ve been in holes, I know how it is. But this was a LOT. Like, I wasn’t sure how it all fit in my nose. It FAR surpassed one mg/KG of body weight and I was winding down off other stuff, about to head to my room for the night. So the six of us in their room all did our line, and laid in beds and chairs. Then suddenly I felt myself falling. QUICKLY. Not like any other hole I’ve been in. Like a speed elevator down, while I’m laying next to my partner in a bed, comfy. But then things got WEIRD. I lost all perception of time and feelings. I would have been terrified, but I didn’t know what terror was. Then I saw it all. It was like the veil of reality was pulled back and I witnessed things that our minds weren’t supposed to see. But I saw them. And I was there forever. Except forever wasn’t a thing, because there was no time.
I haven’t done K since, and that was like seven years ago. It was neat, and also insanely horrifying.
