I read elsewhere, in a site about wicca and magick, that for an obe one way is to get an object with meaning to you (they recommend your crystal ball or wand, but seeing as though I have neither I'll try with my soccer ball ), to turn off all lights (you should still be able to see your object though) and to make your little hoekie wherever you are quiet and indusive to meditation and such.

Then you get in position (lying down, sitting, whatever does it) and stare at the object intently, concentrating on it. Keep doing this while your body relaxes, going to sleep, and ignore evrything else just keep your mind focused on the object. It may not work the first few times (as with everything else it takes practice and perserverance) but keep staring and eventually your body will fall asleep and your eyes will close, but you can still see the object and your room. Then get up and you're out of your body.

I've never tried this, seems like it could be lucid dreaming too, maybe it works for you. Give it a go.
