Ghost Ladder Caught On Camera

I don't know what kind of Paranormal Activity Voodoo type stuff is going on in this video but it freaks me out. I had to rewind and rewatch this ghost ladder video a couple times to fully grasp what is happening here. A man records a (ghost) ladder that is slowly (but surely!) moving its way down his driveway. Can anyone explain what is going on here? If you have answers, share them in the comment section below. After my first watch, I assumed it was the wind... BUT... the trees in the background aren't blowing. Sooooo....... your guess is as good as mine.
