I experienced something of this over the weekend. i think its probably the weirdest headspace you can put yourself into...
It was simply a very very strange experience though, and coupled with lots of deja vu. I don't do ket a lot but it my trips often have a dark or creepy feel - I remember thinking of the fact that I would be alive tomorrow, but found it so hard to relate to that idea that it was completely unnerving etc
I'm interested to know other peoples views on how much it can actually be used in a psychonautic sense. It can do some fascinating things the way it can seem to separate your mind from your body somewhat...but its nothing on the ego-loss of LSD or pslocybin: I think going into the session with expectations more of the latter was one of my mistakes. The whole things really been a lesson in how you won't find what you're looking for with these experiences, if you don't do away with that very notion and surrender to total openness; henceforth drugs can often be just as much of an illusion as anything else.
I've had lots of amazing ket trips though, and the experience wasn't even entirely bad. Its come at a time of spiritual realisation for me, and I'm now aware of the fact that drugs aren't even needed at all to be fulfilled and happy (not that I won't go on to have other beneficial experiences with them). This is something I seemed to have moved away from since my very first psychedelic experience with LSA - which really confirmed the bliss of synchronicity to me in all its glory, the gut intuitive of finding truth and whatnot. Since then I've experimented with LSD a few times and had equally if not more incredible trips, however I find a much more psychological effect generally perpetuates, that could be said to detract from the purely mystical and awe inspiring un-veilings such as I've been given with LSA, Mescaline, Shrooms and Salvia etc (all be that on Salvia I wasn't ready for her at all hehe). So, a difference between natural and man-made substances perhaps?
Of course its only if you *let* your psychology affect you in this way, which I've simply realised I have been doing lately. If anything this is a good example of how bad trips are always down to the person themselves rather than the substance, and that self-doubt and negativity is ultimately useless and irrelevant to the cause of love. I guess its also an example of how you can learn a lot from bad experiences heh. Just been permanently fooked for too long and need to sort my head out basically, which is the usual conclusion with these things
*back to lurking*
