Oh I forgot to add that there was also this really strange strobing effect going on in the dark..like really fast flickering of reality,reality flickering in and out..I have had it before but never like this..it's facinating and I got the feeling it wanted to give way into something much more at a larger dose..Really close to the way Ott describes it..made me feel sort of like I was on the verge of an OBE as well..
