I had a sort of strange experience yesterday. I was in the kitchen and I was staring out the window that had the shades sort of closed. As I watched, a figure of my friend walked by. I could only see his top half, and I was wondering what he was doing here. I went to call him on his cell to see if I could hear it from inside, but no one picked up. Later he called me back and I asked where he was,he was in the car with his family going somewhere. i asked him if he passed by my house, and he said no. I thought he was lying so I told him what he was wearing. I got it perfectly right. The time that I had called him, was when he was sleeping, so that is why he did not pick up. But whats intresting is how I saw someone who looked exactly like him, wearing the exact same thing he was, walk by my window? Wtf was that?
You say that he was sleeping?
There are two possibilities:
1. He was there, and is making fun of you
2. He really slept then, and had astral projection that he doesn't remember, and you saw his astral body - this is possible too, I've had similar situation once:
I've seen someone floating(?) behind the window - it's on the 2nd floor of my house.I've thought that it is a hallucination caused by the lack of sleep, or brain damage(I've had some kind of a brain disease recently, I don't know what's name for it in english...), so I didn't say anything. 10 minutes later my brother saw the same person floating behind the window - he is perfectly healthy, so this was not a hallucination. Later we found out that it was very powerful neg, it attacked my brother, running away after he reached state close to OOBE.
Sounds like to me, you saw his doppleganger(a ghostly double of a living person) Or he projected and didn't know it, and you might have polyvision.
