We have a ghost in our house. He mostly spends time in my daughters room. On more than one occasion I've gone in to find her there, sitting quietly on her bed. I ask what she's doing and she says "the man was keeping me company".
There was one night that 3 of us had encounters with the man, without knowing any one else had also.

But, here is the weirdest: We were vacationing in CapeCod and my husband lost his keys in the ocean. The problem was that he had the only copy of a key to our toyota. We went home a day later, and walked in the house throught the kitchen. The counter was completely clear. I walked to the end of the room and turned around...just in time to see the key drop onto the counter. The rest of the key chain has never appeared.
