I just watched this and was very surprised to see that they used clips from my Youtube series "WATCHER"...wondering why as my youtube series is not Slenderman related?

I did recognize the video in this docu/film. I Saw ur video somewhere on youtube with 5 most scary etc etc.
Thought it was weird seeying it in a slenderman related docu. On the other hand ... it could have very well been that the person standing in front of that Window for such a long time ... wanted to scare u or the one that made the actual video, pretending to be slenderman
