The Daily What finds a single-serving site:
“Internet K-Hole” — a fascinating, seemingly unceasing time capsule of random, caption-less snapshots and Polaroids from the 60s, 70s, 80s, and 90s. The lack of context is what makes this collection far creepier than it would otherwise be. (NSFW, the good ol’ days.)
For those unfamiliar with the term "K-hole":
At sufficiently high doses of the drug ketamine (often .25 grams (0.0088 oz) – .5 grams (0.018 oz) or more), it is common to experience a "K-hole". This is a slang term for a subjective state of dissociation from the body which may mimic the phenomenology of schizophrenia, out of body experiences or near death experiences, and is often accompanied by feelings of extreme derealization, depersonalization and disorientation, as well as temporary memory loss and vivid hallucinations.
