spiritual realm

I’m afraid the spiritual realm is the same as astral realm, unless your referring to the etheric realm. Here is the difference. Most Out-Of-Body Experiences, especially those that are spontaneous, occur on the etheric plane. These experiences are also sometimes projections because the etheric plane resides so close to the physical plane that physical surroundings are perceived in real time. These experiences would be the typical descriptions of floating over and seeing the physical body. Self induced OBEs can also take place on the etheric plane. The astral plane resides just above the etheric plane, and OBEs that occur on this plane may be more mistaken for dreams due to their obscure and mystical nature. It is believed that these OBEs , can help us access multitudes of information about our existence and the underlying workings of our own physical world. Thought can also induce imagery here, adding to the mystical qualities of astral projections. Dreams are believed to be astral projections.
