Not on ketamine but mxe.
It's like your soul detaches from your body and goes on a journey on it's own while you know and can feel that you can't move.
Enter the void is great watching when you enter a k-hole.
Same. I've never tried Ket, but MXE was meant to be quite similar with the dissociative effects and with the possibility of Out of Body Experiences.
An OBE began to happen to me on one occasion after taking MXE, it felt like my mind (consciousness) sort of detached from my brain and skull, and then it hovered just outside and just above, and then it rose about 1 meter above my head. It felt like my mind was attached to my head with what felt something like an invisible elastic band. Unfortunately though I freaked out when this happened, I wasn't relaxed enough to just go with it and let it continue to happen, and when I freaked out it felt like my 'mind' quickly snapped straight back into my head. The OBE, if that is what it was, was over very quickly. .The whole thing was probably just a few seconds.
I mean, these things are so weird, and I had / have fears like who is to know that that wasn't the beginnings of real death experience, actually dying. I have no idea if an OBE is part of dying. There certainly seems to be such a link in certain types of films, when they try to depict the process of dying. I guess an OBE might be scary for many people. Obviously more so if unexpected, but less so if you're looking for it and prepared for how to deal with it.
Maybe going slightly off topic with this final bit, apologies if so, but I do find OBEs interesting, and I've known a couple of people IRL that have had them.
Neither person was triggered by Ket or any known dissociative substance. The first guy I knew had had many OBEs, with his consciousness floating around the ceilings of his parents house, the direction of it under his control. The 2nd person I knew told me she was triggered by Valerian Root after I suggested it to help with her sleeping problems. Never heard of that association before. I have no reason to doubt the truth of what either person said. I know some people are sceptical, and science itself is sceptical that OBEs even occur, because nobody has been able to scientifically prove them, the last I heard. I don't know if there has been any development on this in recent years.
When I did my Psychology degree many years ago, one of my lecturers, Susan Blackmore is an expert on this whole subject of OBEs and consciousness. She'd been taking KET herself for the purposes of studying its effects on OBEs within herself.
