I had a similar experience with ketamine. I accidentally did a line that was a little too long and k-holed for the first time. During the trip I convinced myself I went insane and that I would have had to live the rest of my life inside the mind of an insane person, with no chance to ever experience the outside world again. But I was ok with that, I was like “well, it happened. Nothing I can do about it. I just got to roll with it now” lol. Then I snapped out of it. Never touched ketamine that weekend again, but the following week I wanted to repeat the experience.
Ketamine is not a psychedelic but a khole can make you experience stuff that maybe only DMT can. Illusion of timelessness, lack of physical dimensions, absence of linearity in time and space, it’s something I’ve only been able to experience during my first k-holes
