Shadow is a term used in psychology to describe parts of our personality that we don't like or don't want people to see. It can be made up of qualities like anger, sadness, and fear. Think of it like having a pair of glasses with different kinds of sunglasses. Depending on the situation, we can choose which pair of sunglasses we want to wear. The glasses with the darker shades hide the parts of our personality that we don't want other people to see.
