I think astral projection can be done by many people. Those take place in the two lower heavens of lower and upper waters -- or as they are called in other places water and air. Anyone who dreams about flying means he has "wings" of some sort. That places him in the middle heaven of air -- much better than the lower level of the sea Of course, you don't really need wings to fly. Getting to the Third Heaven is a little harder. "Something" needs to "come down" to get you.
Now if you are in the Third Heaven (of fire) and want to show up on the lower levels -- or even to people in physical bodies, you shift down and "appear" in a cloud in the region of air or upper water. You don't need to fly at all -- you visualize the space you want to be in and make a body appear there. Thus you really can be in two places at the same time as Jesus said. He said he "came down" from Heaven but also said he was in Heaven too.
John 3:13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
I had an amusing experience once when returning to my body. I forgot I had moved my bed. Instead of slipping easily into my body when I got back, I got disoriented. I looked around the room and didn't recognize it at first since I was in a corner of the room -- looking at the room in a way I had never seen it before since my physical eyes had never been in that corner looking at the room.
People have opinions about the astral plane, often without seeing much of it if any. Our souls can visit there while our physical bodies are asleep; but then too, there are "things" on the astral plane that would like to show up in the physical world. Can they? They try. Some do -- coming up out of the "sea." It is very hard for them to "appear" to our physical eyes although they would love to do it, but they can still interact with mediums, wiccans and the like. Yes, some of them also can chat with Christians deceiving them.
