I would not say elves, I would only say aliens... if they are elves, they are elves from another dimesion so that makes them aliens that look like elves, but aliens nonetheless....the problem with the question is that if you ask me 5 minutes after a trip i'll tell you no doubt aliens were communicating with me, but just an hour later i have convinced my rational self it just couldn't be.
My feeling is we are being communicated to from another dimesion at all times, and it takes place on a wave closer to the speed of light, and with spice we are able to think or see at that higher dimesion.
Perhaps our brain (pineal?) is a receiver of intelligence at all times, like an antenna, intelligence of a basic order that is communicated via shapes, only the density of that activity is increased on dmt.
... or maybe it's just that it's been less than five minutes :O
