Are aliens, at times, really ghosts? Or entities? Or the other way around? Do they imitate each other at times; if so, why? Is that the Trickster at work, mimicking one or the other, to confuse? After all, that's what the Trickster loves to do.
Sometimes entities of some type seem to imitate ghosts and aliens. There has been some interesting discussion about what we consider 'aliens' (meaning extraterrestrial) mimicking ghosts. (What we think of as ghosts.) And what about 'shadow people?' which some researchers believe are ghost like, but not ghosts; entities, but not aliens. Of course, no one knows for sure.
There's also a UFO/entity-alien and Bigfoot connection. Is Bigfoot a poltergeist or, is there a connection with Bigfoot and poltergeists, as Bigfoot researcher Lisa Shiel recently suggested? (Poltergeists: The Other Synchronicity with Bigfoot?).
