Strrange Ghostly Shapes On Video

Some of the shots on this video are amazing. The section with the hospital ghost is the one I thought most puzzling.

The Australian War Memorial clip was not very convincing to me. I was highly suspicious of the two figures either side of the angel (not even sure you could say it was an angel.)

Of course, I might be totally wrong but I am not quite sure that these clips are genuine. I did suspect a bit of tampering.

However, I do believe that ghosts exist in some form, so I cannot simply debunk the whole thing.

What do you think?
