Kitchen Ghost?

We've always known we have more than one spirit in this house. One we call the kitchen ghost.  She or he is in the kitchen quite often. Either moving things around. Banging on pots or dishes. Touching R on his back while at the sink! The kitchen ghost has appeared as a white mist to me. Once I turned from the sink to the refridgerator and walked right into it!  The other night I was rinsing the dishes off to load into the dish washer, R was in the family room on his mac and no one else was in the house.  I kept feeling a presence behind me and of course when I looked around no one was there. This feeling happened several times but wanting to get the dishes over with I just ignored it.  On this particular night the overhead sink light went out so it was a bit darker where I was standing and you would think it would be harder to see shadows right? Wrong.  As I was half way done I felt a strong presence again and automatically glanced over to my right and there on the kitchen counter was a dark shadow! I could clearing see the outline of a head, neck and shoulders.  All I could say was, "oh gosh!"  And then it was gone.  I called out to R who was still sitting in the other room and told him what I just saw.  He came over and I showed him where the shadow was and we tried to recreate it.  R would stand in different spots until his shadow was in the exact location as the dark shadow I saw.  We concluded that it was if someone was standing right behind my right shoulder to cast the shadow in that spot.

The day before yesterday I was on the computer with my back to doorway from the kitchen.  I heard footsteps coming towards me and then heard them enter the family room that I was in.  Without looking I asked who it was.  No response.  I turned and no one was there nor in the kitchen.  Then I realized I was all alone in the house in the afternoon!  Just another day at my house.
