Ghost Through a Brick Wall Observation

Watching the YouTube video, I carefully observed the footage to determine the possible answer. While it did look human, the statistics show that it's possibly the frosty air flowing against the wall. It's impossible to see if it was a ghost. I'm no expert when it comes to ghosts, but if you were to ask someone from Ghost Hunters, experts on paranormal activity, they'll give you an analysis. Some people have one opinion, all different from the other. In my opinion, I say: HOAX.
