Is it too late to answer the OP? Because I did have an experience with a ghost.
Some orchestra friends and I were at a restaurant called The Country House, in Clarendon Hills (suburban Chicago). I didn’t know at the time that it was rumored to be haunted; our group just went there after rehearsals because we liked the food and it was open late.
Six years ago, just before Halloween in 2002, we were hanging out there as usual and talking about our plans for our upcoming Halloween-themed concert. All the musicians were going to wear costumes, I was doing some paintings, yadda yadda buncha details.
And I said something smart-alecky about ghosts. The President of the orchestra gave me a funny look, which I didn’t understand, and I said something else.
Now, we were there late, probably 10:30. So the place was almost empty - most of our group had left, I think there were just 4 of us remaining. And it was cold out, the windows were closed. I was sitting at a big round table, the rest of our group was at the adjacent table. And we were just sitting there, talking; no servers were running around. Very quiet.
As soon as I made my second snarky remark, the red bowl-shaped glass candle-holder in the middle of the table flew off to the left and landed on the floor, shattering.
There was no reason for that to have happened. Nobody walking. No wind. The table wasn’t wobbly, we checked afterward. I had my back to the kitchen door and the room was crowded with tables – if someone had been in the kitchen pulling strings, it would’ve taken a LOT of strings and some dollies to rig up an arrangement at that angle. We didn’t find anything.
Our waitress heard the shatter and came out from the kitchen. She was quite unsettled by the incident.
:scouts honor: that’s exactly what happened.
