well also if you happen to run into a skinwalker...I can't remember exactly what the Hopi said about them let me check...
I couldn't find a good description other than wikipedia and I'm sure everyone can do that themselves

It was black and hairy and was eye level with the passengers in the cab. If this was a man, it was like no man Frances had ever seen. Yet despite its
monstrous appearance, whatever this thing was, it wore a man's clothes. "It had on a white and blue checked shirt and long pants - I think jeans,"
Frances testifies. "Its arms were raised over its head, almost touching the top of the cab."

That's a first hand encounter with a supposed skinwalker, I can't be sure if they exist or not. However, I have spent some time backpacking with a
group in the Utah desert and it definately gets a little creepy at night. A few weeks before I arrived there, one of the instructors and around five
kids saw a UFO fly above them. About a minute afterwards several low flying Stealth Bomber's flew overhead (distinct yellow lights on the bottom that
I have seen for myself while in the desert they fly very fast and low) and then later fighter jets and then finally what looked to be a radar plane
with a bubble on top. Now keep in mind this is October of 2004 at night and there shouldn't be this kind of activity in a random part of the desert.
They were really out in the middle of nowhere, not a person for miles.
So if this kind of story can happen (and you believe me) why not a skinwalker? There are a lot of unexplained things in this world that can simply
only be described as paranormal. Just leave it at that
