I respectfully disagree. There are ghosts.
For certain
I was in Tours France about 4 weeks ago for business in a very old hotel (had been visited by Napoleon, Churchill, and a ton of other notables,I’d give it 3.5 stars) on like the 6th floor or so and at 2:30 in the morning someone grabbed me by the shoulder and pulled me partially up out of bed. I’m fairly certain I hollared out loud. Pulled the hand off turned looked - nothing. Turned all the lights on nothing. But I could feel something toward the window watching me. Sat up the rest of the night talking to it - said a few prayers as well. Funny thing is I’m not sure if he (the feel of the hand on my shoulder was a guys) understood a word I spoke - after all he was likely French. Likely the scariest thing that I’ve ever had happen to me - worse then the car rollover, etc.
In the 80s coming home from work one night (Thursday 13th full moon not a cloud about 10pm) during high school I ran over a large cat by the old town graveyard - it was coming out of the drainage ditch across the road. The Ford Escort I was in lifted up on both front and back wheels so I knew I’d hit it and hard. Got out of the car to see if I could ID it and notify the owner...it was a small town...nothing, no cat, no stains, no fur, no prints. I went back the next day nothing. It was just gone.
