Well, this is an interesting topic.
I have not had much happen to me personally... other than the last mobile home that I lived in had 'echoes of the past' in it.
I would hear, late at night... around midnight - or even after - footsteps running through the house. Now, to me... it sounded like sound travelling through the ground, and coming up into my mobile. I figured it was from a neighboring mobile. The footsteps were like a little childs'. Running - Pause - More Running.
When I moved to my new mobile... I have never heard those footsteps anymore. I have come to the conclusion that the mobile home had 'absorbed' the sounds from through the years... of all the occupants... and had slowly released some of the more noisy ones - late at night.
(I had found a boys' hot wheels under the fridge when I moved in, so know that previously, a boy had lived there as one of the occupants.)

My daughter had an experience -
One evening, long ago - when I was still married - my wife and daughter came out to my shop/office, and asked if I would go into my daughters' room and turn on the light. They were both pale. (They are also both JWs - and firmly believe in 'demons'.)
According to my daughter, earlier that evening she had walked into the room, and reached for the light switch, and heard a man's voice - low and deep saying, "Come here, bi**h!". She freaked and went to my wife, who also freaked - and they both came to me - figuring that a man was in that room.
Well... I ain't no 'hero'... and this didn't sound like someone (if there _was_ a man in there) that I wanted to tangle with. But... I went inside, and went down the dark hall to my daughters' room. I reached inside and flipped on the lightswitch. Nothing there.
I then went to the living room where they both were... discussing what items might be 'demonized', and such.
I asked again, exactly what she heard... if her radio/stereo was on or not (it wasn't), etc. I knew that there had to be a logical reason for this.
It turns out that there was. The neighbor fella had a friend who would come over and visit. This friend had a CB radio in his car - with a linear amplifier. Whenever he would 'key' the mike, he could broadcast to California!
I figure that he was in the middle of a conversation with one of his fellow CBers, and it happened to come through my daughters' speakers - using the speaker wire as an antenna.
But at the time... they were BOTH spooked... and I was too. *grin*
