Your message above mentions the scrambling around on the rooftop. The home I built and moved into 2 years ago, overlooks a very large slough. When looking into the history of my property I found out that initially this was local indian hunting grounds. No one, on record has ever lived here before. As soon as I moved in I would hear something "scrambling" around on the back deck of my house. For some reason, it made the hair stand up on the back of my neck. Every time I'd investigate I'd see nothing. This would happen any time of day or night. My dogs would go nuts, nearly frothing at the mouth when this sound would start. They don't have direct access to the deck so they just flip out. I tried to come up with a reasonable explanation. A cat, a dog, racoon, oppossum, fox, coyote, deer, elk, crow, sea gull, cougar, bear you name it. I have yet to catch what ever it is.......but the last time it happened the sound began on my deck and it traveled to my roof. It made an awful racket. I froze in my tracks and couldn't move. I'm not skiddish or nervous but I could not move. The scrambling sound went on for about 5 minutes then I heard something drop to the deck and run.....it sounded like two feet running and not four. The word scrambling is the only way I've described this to my husband. Since I've been reading these posts on skinwalkers and such it really makes me rethink things, especially when I become so immediately immobile. I've come upon coyotes and a mother black bear w/babies on my property and of course it startles me but it doesn't freak me out....not like the scrambling noise does.....I just found that highly interesting, I guess I better educate myself a little more on the native Americans who are from this area.
