I was lying in bed last night, when to my surprise I noticed the screen of my monitor was emitting a greenish-grey glow. Thinking that I'd just forgotten to turn it off, I stumbled over to the light and switched it on. The monitor was off. I turned the light off again and it was still glowing. Slightly worried, I pulled out its plug and repeated the experiment. The glow was still there.

So I've come to the only logical conclusion - there's a ghost in my monitor. I'll have to phone up Dan Aykroyd and ask for an estimate. In the meantime I covered up the possessed monitor with a towel so that I could sleep without its unholy aura disturbing me.
