OBE = put of body experience. I'm not too crazy about them. You feel like your falling but you look back and you lying in bed sound asleep.
It is distinctly different to lucid dreams. You seem to be even more lucid... and you know when your no longer traveling you suddenly find yourself back in yout body... you know the session has ended. Whereas with lucid dreams you can just lose lucidity in the dream state and continue dreaming.
