Are paranormal activity fake?

Some people believe in ghosts and paranormal activity, others don't. Here are some opinions from Answers.com contributors:
  • No it's real. A lot of types of paranormal activity can be explained by science like cold spots/hot spots and orbs in pictures could be dust particles but how do you explain a chair sliding across the kitchen floor by itself or an apparition in a closet doorway? I haven't found one yet.
  • Paranormal activity cannot be explained by science that is why it is called Paranormal Activity.
  • It is not proven to be real or fake, it is usually up to the person. There are sights you can find that will show videos saying it must be real but then the other sights will show videos proving it is fake. It is completely up to your own thoughts and proof.
  • Paranormal activity is very real and in fact all around you. I would recommend looking in the Weird series. (weird Pennsylvania, etc) you can find credible info on all sorts of paranormal activity.
