My name is Sean and this happened to me almost 2 years ago now. This took place in Bangor, Maine in my old apartment with my fiancee. The place was definitely haunted. One thing about the place was the bathroom mirror. You would get zoned out if you stared at yourself too long and eventually your face would start to distort and look odd. My fiancee lost over an hour on a few separate occasions to the mirror. It was really strange how it pulled you in and made you want to stay just to gaze into your own emotionless face.
But my story is about this one night that actual activity occurred. My fiancee and I were in the living room probably watching something on the computer. We were not on any drugs nor were we drinking, just hanging out minding our own business. All of the sudden we hear this loud BANG! Just a loud bang that came from the kitchen. We look at each other like ummm what?... And proceed to investigate. She enters first and I am quickly behind. I find she has been struck frozen in horror. I then follow her gaze to the kitchen cabinets, all of which are slightly ajar at different levels of openness. It took me a moment to realize what had happened. All of the cabinets had simultaneously slammed open with such force that it made a single very loud bang. At that point we both were just kind of in shock not sure what to do. We ended up just leaving the cabinets and the kitchen for a while. Nothing else ever happened but apparently something wanted our attention that night.
I'm not sure exactly what was happening when the cabinets slammed. I wish I had a more specific memory. I'll never forget the look on my fiancees face though.
