Reflection in a shadow!

My bed is next to the wall so if I sleep on my left side I can see my shadow on the wall. So this is what happened.

I'm not sure about this but sometimes I feel I'm trying to be abducted/carried whatever but since I'm a really light sleeper and tend to wake up at the slightest noise, action etc it doesn't work out. I get this feeling.

Anyway, back to what happened last night. I was sleeping. My dog was with me too. He was sleeping on my knees. I don't know what happened but at that point of time, I was half awake and since I was sleeping on the left side, my eyes focussed on my shadow on the wall. Here's the strangest thing. I saw a reflection of a being coming towards me, through the shadow! How did that happen I don't know, but I was still in my sleep so I continued to watch anyway. The being stopped near my bed and reached out its arm to me. Then suddenly, the bed starts shaking...or was it me shaking? It wasn't shaking violently, but it was doing what it could to get my attention. I wasn't fully aware of what was going on and I felt a strangeness around me as I was shaking. After a while, the shaking stopped. I was full aware again. I got up. Everything seemed normal. My dog was asleep. Weird...!
