I've never had words to describe psychedelics very well, but DPT is extremely bizarre. I'd compare it to DMT but truly, its not all that similar. DPT is a bit darker, a bit more alien. On the highest doses I've had I experienced the similar degree of reality shift as with DMT (ie. take drugs in quiet room, suddenly outside in the desert a million years ago), but with less stability- I recall zapping about through all these different places (whilst lying on my bed) and I kept zapping into a true OBE scene, watching myself lie on my bed and then suddenly zapping away again. Possibly the most interesting experience had me surrounded by the OM vibration, both hearing it and feeling it, and as I came back to reality for good, I saw the OM symbol really plainly behind my eyes.
