Earlier today I was standing at my Spamalamadingdong window watching some lizards feeding in the garden when I saw a reflection of a tall, thin man with no shirt pass slowly across the window. As I watched this I was thinking that the hubs has suddenly gone "stealth" as he usually makes all those old guy noises when he moves. I turned to talk to him and he wasn't there behind me. I found him still taking his shower and was no where near the Spamalamadingdong.
When he got out I asked him if he had gotten out of the shower and he said, "no". I asked him to walk behind me as I went back into position at the window and he did but he did not cast any reflection, shadow or anything in that window. Now I was REALLY intrigued as I know danged well that I saw a gray reflection of a man, plain as day walk slowly across that window. No one was outside and my house is too far from the street to see anyone of that size, from the waist up as a reflection. I hadn't moved during this sighting either so I know it wasn't me.
I can certainly say that I can understand how people can see ghosts like this. If I had a video camera shooting, it would have been great. What I think it was is a large turkey vulture flying overhead, casting a shadow on the garden.
If I see it again, I'll see if I can start a conversation with it.
