Wow sounds cool. I think I had an OBE when I was younger, or I was lucid.
Because I was in a place quite like your dream, it was like haunted house type of thing lots of dark purples and dark browns, and I was at my house and I'm like "I must be dreaming....when is this going to end??" I think I waited like 10 minutes it seemed for the dream to end....Yeah wasted exp.
Also if you obe you can like go anywhere? So if I do this I can like think "area 51" and be there?
