A childhood belief about fear of

In my younger days, combined with a SERIOUS fear of the dark, I used to believe there were flushy monsters. These would only come out at night after you flushed the toilet - when there was enough noise to cover your screams. Fortunately I had a process that kept me safe - first, turn on the bedside light, then turn on the bedroom light, walk down the hall to the bathroom and turn THAT light on, then finally turn on the hallway light. Hop on the pot, do your business, but BEFORE you flush the toilet, quickly turn the hall light off. Come back to the bathroom, and with one hand on the flusher and the other on the light switch, flip both at the same time and make a mad dash to the bedroom, flipping off the bedroom light as you passed. Hop into bed and cover everything but your eyes, then lay as silent as a rock... if nothing came to get you, it's safe to reach out an arm real quick and turn off the bedside light. This persisted for years, and is probably the reason I would occasionally wet the bed until I was seven!
