Unexplained walking on roof

Ok, so my tale dates back to the fall 2006. I was sitting at my computer working around 2-am next to a couple of windows in a 2nd floor bedroom facing the woods. We’re right up against the woods in fact on the Talcot Mountain area. Anyway, I hear a super loud BOOM like something HUGE landed on the tree right outside the window.

Simultaneously, I heard all the leaves on that tree shake and the tree branches literally GROANED under the weight of whatever it was that had just dropped or landed on that tree. I was PARALIZED and couldn’t move. I was just sitting there bewildered by what I heard.

What happened next though really freaked me out! Whatever that thing was then jumped right on to my roof and started walking! This thing was bipedal and walked on two feet! It was loud like it had on boots or something. I ran out of there into the next room and locked myself up.

That was 20 years ago and I never heard the walking again until maybe 3 years ago when I heard walking back and forth right above my bedroom. I just prayed and prayed for protection and it ended after about 1/2-hour. Again, this happened around 2-3 am. What are we dealing with here? Mothman? Dogman? Other? Anyone else have similar stories?

I would also note that a few months after whatever it was that landed on the tree, the tree dried up and died, which is weird. That has made me think whatever the creature was, it was definitely radioactive or evil to cause death to the tree. Thoughts?
