When I was a teenager, we had just moved into a modest 3/2 that was about 30 or so years old--nothing ancient by any means. One evening I was in the kitchen and the door to the garage opened slowly, I thought little of it figuring it was my dad coming inside. Well, when I turned back around to the door to speak to my dad no one was there. My dad then called to me from the living room (opposite direction) and the door then slammed very hard. This was immediately followed by a glass container sliding off the rear of the refrigerator and breaking on the floor.
A few years later, a girlfriend of mine was in front of a mirror applying makeup down the hall from me. I heard her call out my name in a questioning way. When I responded she asked who the guy was that was behind her in the hallway watching her in the mirror. (She thought I had let a friend in the house). Of course, no one was there!
That said, have to share mine! I lived in Cripple Creek, CO back in the '80s for a bit. It was one of those gold rush mining towns gone bust. My very first job was at this ice cream parlor on the bottom floor of an old hotel, the Sarsaparilla Saloon. They were renovating the hotel part so it was full of junk, basically. They sent me up there to get some TP for the bathrooms. Of COURSE it was summer and a nice thunderstorm was brewing. So I go up there all by myself and at the END of the hall was the TP. Grab as many as I can carry and start heading back. Then I hear high heal footsteps behind me. Thought it was one of the other workers so I turned around. No one there, footsteps stopped. All my hairs stood on end and I raced down the hall, flew down the stairs and my stack of toilet paper went all over the place.
I read in some book somewhere that there is a long history of hauntings in that hotel. I get chills thinking about it...brrrrrr
