Shouting dream meaning is explained below using 3 different sources. Each interpretation is shown with its source.

Interpretation 1 — Theresa Cheung

Arguments and shouting in dreams, as in waking life, suggest that you are feeling in conflict or have opposing views on something or someone.

Alternatively, they may be simply a release for negative feelings about someone or something that you are unable to express in waking life; in other words, your dream is allowing you to vent your frustration. The dream may also refer back to anxiety you experienced as a child when your parents were fighting and you felt powerless to stop them.

To hear other people shouting in a dream, foretells that you will hear distressing news. However, if you dream of shouting yourself, it is a lucky omen for all that concerns you closely. Also see “Arguing.”
