Why is dreaming necessary for many of us? Dreaming allows us to act out socially unacceptable thoughts and desires and to sort through issues or to solve problems in our daily life. If we don’t dream when we sleep, then we may become sick.
For example, we’re angry at our college professor for giving us a lower grade than we’ve expected or we’re upset at our husband or wife for whatever reason. However, we dare not express our opinion to the professor and we don’t want to disrupt the harmony in the family. Instead, we vent our anger in dreams.
Without the ability to release our anger and frustrations in dreams, we would continue to feel stressed out in the daytime, which would eventually cause us to become ill.
