Ghost stories in class

So today in my COMM 1310 lab, we did impromptu speeches. My teacher had a deck of cards that had different subjects to talk about on each card. She gave us three cards and we got to chose one of the subjects to talk about for a minute in front of the class. The card I picked was about having an experience that made you believe in angels or ghosts. I picked this card because it was the only one that I was able to think of something for. When I got up in front of the class I told them about my first experience with ghosts or angels. When I was about eight years old, I was laying in my bed waiting for my dad to tuck me in goodnight. While I was waiting, all of a sudden I saw three little girls wearing white dresses. They were standing at the right of the foot of my bed. I started to freak out and scream, and when my dad entered my room they disappeared. He asked me why I was screaming and I told him what I saw. Then he told me that they were just my guardian angels watching over me. So whether they were ghosts or guardian angels, I knew I saw something, and I'll never forget what I saw.
