A childhood belief about monsters

The world was full of unexplained perils. There was a blue cow that lived behind the glass shower door. Dad said so. Cedric and Jessica were the invisible ghosts who opened and closed the back door on a windy day. They were good ghosts, but mischievous. The worst, however, were the nightmares. I remember waking up screaming (and my parents remember it too) after dreaming about the Bull-dort, a horrible giant warthog with killer tusks. He rapaged throught the dark forests of my mind.
