Until I was about ten or eleven, I was convinced that vampires lived behind the U-bend of our toilet, and that if I spent too long sitting on the loo that they would come up and attack me.
My sister told me that, unless I did a song and a dance after I had a poo the Toilet Monster would come and get me...
the song went "Ugga Bugga Ugga Bugga Ugga Bugga Ug, Toilet Monster please don't come"
I used to believe that once you flushed the toliet the Rice Crispy Elves would come out of the toliet and attack you and force you to live with them in the sewer.
When I was 8 or 9, one of my friends told me that the toilet talked to her when she used it late at night. for a good 4 or 5 years, I was terrified to go at night. I'd put the lid down immediately, wash my hands, do whatever else I could to do to delay the actual flushing, and then do a flush-and-run. The toilet never did say anything, though, and somehow I was always kind of insulted that it didn't - it would talk to her and not to me.
After my sister and I watched Nightmare on Elm St. at the ages of 5 and 6, we were so afraid that Freddy Kruger would pull us through the toiled that one of us had to hold the other's hand while sitting down. That way, we could help pull each other off the toilet if the hand tried to reach up and grab us.
When I was little, I used to be scared to use the bathroom on the first floor; I had a phobia that Abraham Lincoln lived in my shower.
As a kid, I was scared of things coming out of the toilet while I was sitting on it...a rat, a snake, a hand. The worst was what I thought would come out when I was done using it. I was scared to death of getting shots, and I thought that if I kept my naked bum near the toilet for too long, a mean man would come up and jab me with a needle. When I was through using the toilet, I would turn around as fast as I could, pull up my pants, flush the toilet and RUN! I had to run downstairs and sit on the couch before the toilet was done flushing or the evil shot man could still jab me with that needle. Really stupid, but I still get freaked out when my naked bum is facing a flushing toilet.
In the boy's toilets at our primary school, there used to be 5 cubicles, however one of them never opened. For years everyone thought that a pupil had fallen down the toilet and the cubicle had been sealed. None of the teachers knew we thought this. Anyway, one parent's evening (student-teacher conference) someone's father was desperate to use the toilet so he just opened the door to the forbidden cubicle and walked in. Needless to say there was mass hysteria from the boy in the toilet, who all came screaming out. Turns out that the door had just been stuck with bubble gum. I also later found out that the teachers knew about it, but never told because they liked the idea of an emergency staff toilet that was always free and CLEAN!
I got told once by my friend that he knew someone who died by a hand that came up the toilet and pulled them in! Everytime i went toilet after that i would go armed with a Hammer from my Dad's toolbox. Waiting for the hand to appear... It never did appear! Funny That!
Used to be absolutely certain that if I didn't make it back to my room before the toilet cistern finished filling then The Incredible Hulk would chase me down. Quite what The Hulk was supposed to be doing in my toilet, I'm not sure.
