An Erowid user talks about their challenging experience taking ketamine and entering a k-hole:

“I had no idea what I was, who I was, what it was to be a human or what had happened. But I knew deeply that I had done something very bad. I also felt as if everything was going to end. Nothing from real life existed anymore and I couldn’t recall anything at all. I had no body. Just the same feeling over and over: 'I am lost' 'who am I?'
