When I was in second grade, my teacher occasionally read stories to our class. One time she read a story about ghosts and a haunted house. An hour or so after going to bed that night, I woke up thirsty and decided to go to the kitchen for a drink. As I walked down the hall I could see something in front of me that appeared to be moving. It was a ghostly form, and I ran away as fast as I could right back to my room! It was sort of funny because I didn’t even believe in ghosts, but I was afraid anyway.
A couple of nights later, a bit timidly, I waited until everyone was asleep and then walked back down the hall again toward the kitchen. Whoa—that same ghostly form was there again! What was going on?
It took me only a moment to figure things out. A street light from outside the kitchen window was reflecting off the refrigerator door, causing what appeared to be the presence of a “ghost” moving around. Right where there seemed to be a ghost, there was really just reflected light.
