Accidentally doing too much ketamine and badly k-holing (by snorting) is one of the worst experiences of my life. Maybe the worst. It was exactly as you described, it's like you're being cut off from reality and have no way back. It's like being plunged into the bottom of the ocean, darkness, everything real is distant, you try to move but you can't - it's like someone has unplugged all your sensory organs and limbs.

And it comes in waves -- just when you think you're coming out of it, it pulls you back down.

I swore off ketamine for life after that and don't plan on ever touching it again. I would take a bad comedown from stimulants over that. I would take the feeling of hopelessness, anhedonia, and thorough depression from a bad MDMA comedown any day. To be fair, both things only happen if you do too much, it's avoidable, and it was entirely my fault for not weighing the dose.

And I still think therapeutic ketamine for depression should be studied and trialled and legal. But still, K-holing was an absolutely horrifying experience and I don't recommend it to anyone for any reason.

And it probably was only not even worse because I was also on MDMA.

It can be absolutely wonderful if you're properly prepared though, just lying in your bed with a dim pink light on listening to Carbon Based Lifeforms or something, enjoying escaping your body for a while and floating around in an undefinable sea of warm nothingness.

However, it absolutely sounds like it could be hell if you're not prepared though - especially in police custody, but even just fighting against it in a party situation where you want to exist and be social could be problematic.
