I used to take quite a few drugs recreationally and I can quite honestly say that Ketamine gave me 'God like' experiences unlike anything else I have ever experienced. Repeatedly (and reproducibly) I could 'see' everything in the universe from the smallest particle to the planets and solar system in one go. I could comprehend nature, science and space and observe everything working as a system, from a point way above it all (it is dissociative after all). It made me euphoric and happy and when coming down from the experience I could (and still can) remember that feeling and how powerful it was / is. Of course to an observer I was basically asleep in a chair.
I had a somewhat different experience. I thought that I had stopped breathing and that my heart had ceased (in actual fact my body was numb - I couldn't feel a pulse) so I stood in front of a mirror completely naked for the next 20 minutes staring at my chest. Thankfully reason stepped in and I managed to compute that if my pulse or breathing had ceased, I'd be in a heap on the floor rather than obsessing in front of a mirror. Suddenly I felt calm and proceeded to throw out some cool graphics in Photoshop and made an excellent puff pastry quiche. Again, without clothes.
My lesson was that drugs should be experimented with in the company of a friend or partner.
Just to add my ketamine experience, I broke my arm a few years ago. I split both the bones in my left forearm clear in two. At the hospital they set it and gave me ketamine while realigning the bones and putting a cast on. It was a terrible experience. It felt like time was just going so slowly and everything was out of my control. Terrible.
It is my unsubstantiated opinion that most rec. drugs act to increase any latent emotions or thoughts you are already experiencing. Alcohol certainly treats me that way.
Thus, since you were in an already stressful situation, I'm not surprised that K wasn't relaxing or pleasant.
Did it lead to any scientific, technical, or artisitic accomplishments that you validated afterwars while sober? That is, did you understand anything while high, or did you have a dreamlike feeling of understanding?
This news doesn't surprise me at all.
