Something in the attic window

We were coming back from the store and we stopped in at the West End Service Store. I looked over at the house and in the attic window I first noticed something that looked like an arm and it disappeared. I looked at the window again and this time some big was there, but could not distinguish what it was. I said something to the kids, they looked and seen it and then when Karen came out of the store I said something to her,but no one knew what it was. The color of it though was brown with some black mixed through it.
