I feel there is validity in describing the experience in a way others can relate to, more psychologically than spiritually. Basically what happens is this: Once the Salvinorin binds to KO receptors, it interferes with the central nervous systems basic functions. I'm not a neurologist, so I cant really explain it beyond that. Basically there is "static over the airwaves". The first noticeable physical sensations are throughout the body, a tingling, burning, or pinching sensation. I call this the "rubbery" effect, as I feel as if I'm being stretched by thousands of little rubber bands. Also comes the "puppet-on-a-string" effect. I feel as if entangled in a giant web, which is holding me against my will, and my thoughts and behaviors are being determined by a powerful unseen force. This is usually when I clutch at a wall or stable object, or turn my head around to orient stability. When this fails, thats when I really start "freaking out" These sensation continue to the brain's core function as well. It is at the point which I feel separated from existence. The "puppet master" is pulling the strings, and they reach deep into the mind. This is when the fear and confusion over the loss of free will set in, and notions of self control are challenged. In as few words, one is confronted with a sense of INABILITY to perform the simplest function, such as standing up or turn one's head, or form a complete sentence verbally, and simply isn't tolerated. This is when I tend to get frustrated and angry at myself for having done this to myself. One is bewildered at the presence of this strange "puppet master", which is actually one's self, which one has become a stranger to. The "strange beings" occupying one's mind are actually the mind which does not recognize itself without its natural chemistry. Everything flattens out, I'm trapped inside a mirror with nothing behind it, and only a narrow perspective on things in front. This is the mind, seperated from itself. Visually, things are perceived, but not correctly recognized. It is like being blind and at the same time seeing clearly.
now i liked what you said, nice description of the effects. yeah, this is very true, but i'd add that sometimes it's not only the loss of ability to function that terrifies us, but also the annihilation of the media you'd use to function. your body melts with the unity and your ego is gone, so the feeling is not only being unable to DO, but being unable to BE.
