My ex hubby and I lived for almost a year at my Dad's 150 year old farm house and our room was in the original part of the house. One night I woke from a dead sleep in the middle of the night and saw an old man standing in the corner near the foot of the bed. I just sat and stared for at least a minute, then suddenly hear my ex (who I didn't know was awake also) whisper, "Do you see him too?!?!?!?" I responded yes and we both watched for a few more moments before he vanished. Freaked us both out.
Also at that same house both my son and my nephew have been playing upstairs at different times and asked who the old man upstairs is, or stated they didn't want to play up there while he was watching them. He seems harmless but the ghost in the barn is not. That ghost also freaked out my ex when he was working in the garage in the lower part of the barn. He heard footsteps walk steadily across the upper section of the barn above his head, all the way from one side to the other, then start again. That same ghost scared the bejeezus out of my BIL when he went to get some stuff stored in the loft and it start pushing boxes over behind him. Literally, he walked down a 8 foot wide path, heard a BANG, turned around and saw a heavy box right behind him. Then as he took off back down stairs, like 3 more things, boards fell over or moved. They had been totally stable for months and there were no animals up there.
Needless to say, I mainly stay out of the barn now when I visit, but the old man in the house seems to just be watching over things.
