I was afraid of the number
0 and the letter
Z. I believed that if
Sesame Street was ever brought to me by those
characters, I would instantly
die.
I also believed that the grandfather clock in the hallway had a trap door next to it, which would use some sort of attracting force to make me fall through it if I stayed in the hallway too long, and that at night the clock would roll around trying to find a way to get up the stairs so it could catch me unaware while I was asleep. (I did, in fact, hear a sound which was like rolling - the sound of the furnace turning on.) My parents wondered why I always ran around the house so quickly.
This belief was reinforced by my nightmares, which were the reason that I ran away from lucid dreams when I was younger.
