Do you believe in ghosts?

Phantasmic goings on at my parents place. My folks live in quite an old house, which was itself built from the stones of a yet older habitation. Builders recently eliminated some damp problems and seem to have released one of those souls who has not yet found his or her path to paradise or wherever it is one goes after vacating one's body on this earth.

So far, my dad has been shoved on two occasions, although nothing was seen to be doing the pushing. And both my parents have seen, at different times, a strange blue globe about the size of a tennis ball drifting along their upstairs corridor. At times my father hears doors closing and while we were staying my other half asked who had been shifting furniture around in the room beneath her. I knew that my mother had been passing through the room under where my other half was sleeping, but my mum did not move anything around, even if she did set a mouse trap, which is not generally one of the noisiest of operations, at least not from my experience, that is.

Ghosts?! Who knows? Strange? Very. Right, I'm off to haunt the sofa for a while to see if there is anything good on the telly.
