I need to know what people think this thing was.
My friend and I were driving in the woods listening to music at night and we noticed a car on the side of the road. It wasn't on but there was something in the driver's side. At first it looked like a white headrest cover or something like that. My friend who was driving suddenly speeded up away from the car, terrified. He said it looked like a face under a white cloth and he could see some facial features underneath it. Soon we laughed it off thinking maybe he was just imagining things. After a little while we decided to turn back to take a better look of it. It was still there. Now i could see the face too but not as well. My friend again speeded up and was even more terrified. He saw it now for sure, a face. There wasn't just a cloth on top of the face, it was wrapped around the head tightly. He could see the face had it's mouth fully open under the fabric. We drove off and tried to come up with an explanation, but it still creeps us out.
My first thought was that it was someone having a migraine trying to relieve it, but it seems odd to wrap your whole head up. I really don't know, any thoughts would be appreciated.
