I've had one experience with these guys a little while back. Before taking DMT, when I first read McKenna and his talks of the prankster nature of the elves, I thought he was being poetic. So anyway, I found myself in this blue temple in hyperspace, and the entities there were moving about semi-invisibly as they camo'd really well with the background. They were talking just how you described. Cursing here and there. They seemed to be a bit of a bully nature, but I perceived them as harmless nonetheless. They would turn my vision one way so they could slap me in the face (sort of a hyper-variation on "you've got ketchup on your shirt
). I found their behavior quite funny and was laughing in the middle of the experience. They were very cartoonish and child-like. I haven't seen them since, but I'm not terribly disappointed either
