Weird reflection On the wall

For the past few weeks this image has presented itself on a design board setting against the design wall in my living room, behind the front door. When the sun is at the right angle, or at night from the street light , the light floods through the window in my front door thus projecting this image onto the design board. It's a face!!! Don't know of who, but it's definitely a face. I covered up the window in the front door & the image went away, so I know where it comes from. It appeared a few days after Halloween! which made it very spooky! especially at night. It's just an odd event that I thought was interesting.
