Report 46620: Possible nighttime sighting through a living room window near Potomac

The sighting was thru the window from the inside of the house. The creature was looking thru the living room window right above the halfway point. Which a person can't see past the bottom ledge.That is what scared me. It was moonlit and created a shadow. I had just turned off the TV at that time. We have alot of deer but they are not vertical or that tall. The incident lasted three seconds.
