Once you open a conversation about 'ghosts' it's surprising what comes out. Particularly if you are game enough to relate an experience or two of your own.
My friend and neighbour Rob, a big no nonsense ex army commando through personal experience, believes in ghosts and other unexplained phenomena (but like Indiana Jones, is scared of snakes). After I told him about a few of the weird electrical/ghost effects and other 'supernatural' happenings around my forest home, he to my surprise told me of several experiences of his own. One was when he guested overnight in an upstairs bed and breakfast room. He was very tired and as soon as he flopped into the bed it started vibrating and lifting off the floor jumping and banging about.. that freaked him a bit and when it lifted up almost to the ceiling and crashed back down to the floor, he decided he best sleep on the floor.
At breakfast the next morning the owner kept giving him funny looks and eventually asked "did you sleep well last night?" Rob explained what happened and the owner said that he was the first person to have spent the whole night there since his son had died - that was his son's room and he didn't like people sleeping in his bed.
Like me Rob is a bullshit free zone, he reports events but, as much as posible, leaves the interpretation to the listener.
