Really fast white "thing" in the woods? Ever seen it?

Me and 5 other people were in my friends backyard when we heard a noise in the woods (it sounded like something BIG)..

Alexis and I went to see what it was, when we got back there we didn't see anything so we thought it was our imagination..

Later, we were jumping on the trampoline and Amber saw it.

After that, Alexis saw it, and so on until we all saw it. We sat down to talk about it and figure out what it was. We decided that it wasn't just our imaginations because, even though no 2 people saw it at the same time, we all had the same description of it (fast [only a blur mostly], white, front legs shorter than back legs). We got on the 4wheelers and took turns riding through the woods to look at it. When Amber went, she went alone and when she came back, she was crying. She had seen it close up and it's face was very deformed.

Have you seen it?

Know what it is?

Please help!

Thanks in advance!
