I saw something years ago, that for lack of a better term, I have referred to as a ghost.
I was in college at the time. It was about 10 pm. I was sitting at the kitchen table with a friend. There was a small hallway that led from the side entrance of the house to the kitchen. My friend was sitting with his back to the hallway. I was facing it.
I noticed a light that was appearing slowly in the hallway off the kitchen. My first thought was that it must be car lights from someone pulling up to the house. The house was in a rather rural area and was set far back from the street. We did not usually experience seeing lights from cars, except when someone had come down the long driveway and then turned toward the house. I figured that either someone was coming over unannounced, or my roommates were coming home early.
When I looked at the light, I noticed that it was in a human shape -- and appeared to be an older woman, with her hands folded in front of her. The shape moved toward us, through the hallway -- not a far distance, about 4 or 5 feet total. Then, it faded out. It did not disappear quickly -- just faded. I did not feel afraid, but instead felt comforted. It felt like a grandmother figure was just coming to make sure everything was o.k.
I think my jaw must have dropped, because my friend was staring at my face and said something like, "What? What is it?" Then, I told him in the only words I knew to explain in, "I think I just saw a ghost."
No recordings or pictures. I didn't seek it out. I didn't expect to see it. I can't deny that I saw it. Perhaps there is another explanation of "what" it was that I saw, but I saw it as I described it.
