Each student was instructed to record their dreams that night and turn it into the Psychology Professor, Dr. Sparks, first thing in the morning. Dr. Sparks would then evaluate the content to see if there were any similarities in our dreams.
After reading the journals, Dr. Sparks burst into the classroom and questioned every student about their pajamas. Apparently we had described conversations with each other in a dream state and identified each other by the color and style of our pajamas. Detailed information about a few of the student's personal life was revealed by identifying their pajamas.
