I'd like to think that ghosts do exist but I've never seen anything that convinces me completely (yes I am a most haunted fan too)
Seeing that clip reminded me of a strange thing that happened when I was a kid, it was shortly after my uncle died in an accident at his work, my mum was driving us to see the aunt who had just lost her husband when for no apparent reason the rear door of the car flew open, my mum stopped, shut the door and we carried on wondering how the hell that had just happened, the doors had child locks so I certainly couldn't have opened it even if I wanted to, as we approached my aunts house the door flew open again, it was very strange and a little scary. My mum was so freaked out by it that she tied rope between the door handles on the way back home so they couldn't possibly come open again. It never happened again in all the time we had the car. We always say that my uncle hitched a ride home with us that day.
