Hi gratefulfloyd,
What you have described is one fairly common experience with DMT (myself and others I have shared with having reported similar things). As you delve deeper into the mysteries of science and consciousness, however, I think "out of body experience" may be one WAY of expressing/describing the phenomenon. There are lots of ways to discuss the same things, some extremely spiritual and some extremely scientific.
The interesting this is that you've had the experience. I would suggest learning and reading as much as you can, continue exploring if you are comfortable, and then reevaluating the question with yourself at a later date. What else will you learn, experientially, between now and then?
There are some really interesting chapters in Inner Paths to Outer Space about possible explanations of consciousness (before the angel/alien chapters
).
Some things will come easy, some will be a test
