I have a few questions about Astral Projection.

Can you visit people through Astral projection or spy on people? And can they see you if you do?

Is it your consciousness or your soul that leaves your body during Astral projection?

Are you exploring the physical world/universe during Astral projection (like haunted houses or a spirit that's stuck on earth, for example) or is it the Astral realm (as in a type of non-physical or spirit realm) that your Astral body is exploring?
