I used to believe there was a huge spider at the end of our hall. I couldn't go down the hall without turning on the light at night....and even then, I'd run to my room, which was at the end of the hall.
It never occurred to me the spider wasn't there in the dark since it wasn't there when the lights were on.
I still hate spiders.
