Shadow Figure at 2am / Friend Passing

I rolled over in bed and lifted my eye mask. It was about 2am. I looked up into the hallway and I saw a grey-black shadow of a man's smooth bald head, neck and torso, moving slowly across the wall, coming toward me. I kept wondering what I was seeing. I couldn't think of a light source that would allow something to cast a shadow there. I thought maybe someone was outside on the front lawn, but the shadow was too well defined like whatever was blocking out the light was close to the wall. I wasn't scared, but it left me with a really odd feeling. A few days later I found out a close friend of mine had died on that same night as I saw the shadow figure. Maybe it was him coming to say goodbye before moving on?
