I have lived in my house for 7 years now (it is a very old house) and have always had a "weird" feeling that I wasn't alone. There have been several instances that I have heard noises, that I can only compare to a baking sheet being hit, or a bag of chips falling. Most were investigated by me, to find nothing amiss. But some have not, due to me being to afraid.
I have 5 year old twins whose bedrooms are upstairs. They will not sleep a full night up there. Every night they join me in bed (downstairs), between midnight and 3 am. I have on several occasions sent them upstairs for various reasons and caught my daughter standing on the bottom of the steps, talking to "a ghost" at the top of the steps. She never seems overly scared of it, but she certainly notices it.
Also, when they were smaller I would watch them see something, that I would describe as floating, as their eyes followed it. I have never seen anything. Thus far its been sounds and my children reacting to what they call ghosts.
Now, my mom passed away in Feb of this year, and told me that I would know she was here because she would knock a picture off the wall. That has never happened. But my phone has mysteriously turned on, no incoming calls or messages to cause it. Also, my smoke detector will go off at random times for no apparent reason.
Tonight I was taking pictures of my son. There are a few pics with a mysterious white smokey type of thing in the pictures. After I noticed it I took 16 more pics, none with the same smokey thing. I am hesitant to send the photos with him bare chested as there are too many perverts out there. I would like to send them all so they can be scrutinized, to verify I'm not a loon.
Anyway, that's my story.
