VERY interesting and please keep me posted.
Sorry I did not mean to freak you out. Just trying to figure this thing out that’s all.
Now I'm having a Wendigo moment, LOL!
If you don't know you'll have to look it up but basically it's when you become paranoid over something and it overwhelms you. You feel like someone is right behind you, turn around and no one is there but the feeling won't go away.
I've been in this building, in Greentree a couple of miles outside Pittsburgh, for over ten years. It's in a surprisingly wooded and secluded area for being so close to the city, From my studio I can see into Pittsburgh's West End, across the Ohio river, across the north side and into the North Hills. I have seen some pretty strange things here over the years but this takes the cake!
The wind is blowing a bit but not enough to make that kind of sound. I've heard the wind sounds here and this was not the same.
