I've learned of this technique recently but haven't been able to do it yet. My question is this: if you can send your astral body to another place, then could it be possible to, in a way, call your body back to you and physically go to said other place? It's an odd theory, I know, but for criminy sakes, don't make fun of it; I wouldn't make fun of anyone here just because they had a theory I didn't think would work.
