A few incidents…
I live in a house where three close family members died (and sadly I was the one who found all three).
When I first moved back I had the apartment upstairs. Unpacking my towels I just threw them into the linen closet, very messy. One morning I said that my grandmother would’ve had a fit if she saw what a mess I made of her meticulous closet. When I came home that night the closet door was open, and towels were neatly folded on the floor. If they just fell out how could they have folded themselves on the way down?
Another time my Dad came up, and as soon as we mentioned my grandmother the large cover over the interior doorbell fell off, but didn’t land right underneath -it went straight to the floor of the next room, a distance over 7 feet. Didn’t bounce first.
Fixing up the basement I had 2 sets of workmen quit because of all the “spooky” voices they heard. Possible it was next door neighbors, but the guys all said it was someone right there in the room with them.
I’ve often felt my mattress depress as if someone was sitting on the other side, but that I’ll admit could just be my imagination. A relative who now lives upstairs says she often smells cigarette smoke, a good 40 years after my chain smoking grandparents died.
Quick aside, I have been to Harry Houdini’s grave, but sadly received no otherworldly messages.
Well there is this movie from 1942, Cat People. Or its remake in 1982, with a stunning Nastassja Kinsky, if my memory serves right, and a great song by David Bowie… Millions saw both, but nobody could imagine that.
Few are, unfortunately. And because of that people die. Makes sense if they then turn into ghosts, come to think of it. Then they shake your bed. I would if I could.
This is not Great Debates. 
Is your imagination really that vivid? Do you imagine lots of stuff you can’t explain when you’re not in your house?
One that I will never forget or be talked out of. The first New Year’s Eve after my husband died, I was fast asleep when I heard a big ruckus in the back yard about midnight/1 am. We had tenants that shared the duplex. The loud noise went on and on and I lay there trying to decide how to approach my tenant to tell them to cut it out. Should I go out armed, should I just call 911, I fretted for a good 20 minutes while the noise (fireworks) went on. I was just about to get up and get dressed when I heard my late husband’s voice, clear as anything, say “Leave them alone, it’s New Years Eve.” I went back to sleep.
