They are able to be conscious and aware in multiple places at once, which means the difference is greater than just not having a body, if you see what I mean.
This is my working theory on why that is:
The way the Abrahamic desert cults try to destroy idols indicates that giving a spirit a physical base fully devoted to them IS powerful, and assists them to operate in this realm, and this is also something I discovered myself. But it won’t mean ALL of them is in it, and therefore cannot be elsewhere as well.
