Has anyone ever had dreams suggestive of being a ghost, or a soul "between lives?"

In some of the dreams where I can fly, I feel like I'm living in hiding (as if my powers of flight made me a superpowered mutant that the government wanted to experiment on, lol), and I find myself looking for places to "roost," so to speak...for unused places up, away from people, that no one is using...in the ceilings of commercial buildings, in the dead space around air ducts, in attics or crawlspaces, or even along support beams in big open indoor spaces, like malls or stadiums.

I recall one dream where I was traveling cross-country for some reason, but I was in a strange city, felt tired, and needed a place to rest. I flew above several streets of older row houses, finally chose one at random, flew in through the closed (!) window, and settled down on the attic floor to sleep.

As I said, it's not the first time I had a dream like that. But for some reason when I woke from this one, I thought back to earlier in the dream, when I had been flying around people to whom I was invisible. I suddenly thought, "I wonder if that's how a ghost sees the world...looking for 'dead space' to hang around in, because they can't quite imagine sleeping outdoors."

Of course, that's just a speculation. But I'm wondering if anyone else has had dreams that (while certainly not proving anything) seem suggestive of the possibility of an "afterlife" memory.
