Just ghosts and ET's huh?
Hmm....
Ghosts haven't made a big impression on me, I guess. They lack a frame of relevance. Of course they exist. Now what?
Not a lot of experience with RV'ers, but seems to me, they won't enjoy going where they're not welcome.
"things, entities, ghosts, etc" will tend to go where they get a reaction. Their ability to feel that response reminds them of being here... and vice versa.
"Aye theres the rub".
