At what age can OBE's occur?

oobe = out of body experience

it covers astral projecting, lucid dreaming, near death experiences anything in which makes you come to the realization that your physical body was not involved in the events experienced.

somehow oobe became a term related mainly to astral travel but as you can see it covers a whole lot more.

Thanks, worldwatcher.

Would it be easier to first induce a lucid dream, and then use the "I am getting lighter; I am floating" trick to leave one's body? Or to use OBE methods before entering dream state. I am not able to lucid dream--I was just wondering.

I found a very thorough document describing parapsychological phonomena, called 'DO_OBE', found here (download the DO_OBE PDF). It has example experiences, instructions, and theories, all written by someone who has a PhD.
