When I was young, I was hanging out with my cousins once in a parking lot close to my home. Suddenly my cousins started freaking out and ran all the way back to my place. I asked them what happened and they said they saw ghosts looking out from the house that was in front of us. I spent the next couple of days looking outside my living room window and obsessing over those ghosts. I kept seeing red eyes looking outside the house that my cousins were talking about. I was really terrified but couldn’t stop looking.
Then I saw a car in the parking lot drive away and two of the “red eyes” moved away with it. And that’s when I realized what I was seeing.
Moral of the story: Your brain can play tricks on you.
