To dream of gym class in school represents anxiety about issues you are very concerned with with being the best at. Worries or concerns that a goal will be too difficult or expensive for you to achieve. A very serious attempt to learn everything you can to be a powerful competitor. Obsession with learning how to be perfectly competitive in some manner. Learning to be more physically or sexually attractive to others.
Example: A young girl dreamed of being in gym class with a boy she had a crush on and then finding herself outside the class. In waking life she was very focused on dating a boy she was talking to, but then felt she lost her chance to date the boy because he hadn’t called her in over a month. She worried that she couldn’t compete with other girls to get the boy as her boyfriend. She didn’t know what else could be done to help her get the boy to be her boyfriend as all opportunities seemed cut off.
