Being that I am into paranormal things, I enjoy the show called Ghost Hunters. They go around to see if they can prove weather a location is haunted or not. They once caught a thermal image of a ghost on video. 
Then there’s this video of a camera/sound man being knocked down, hard – by an unseen force while investigating a haunted Armory. He did not trip over anything, nor did any of his equipment hit him – he just flew backward and said he was physically attacked. 
See that video below:
The Ghost Hunters rock!
