To dream of a gorilla represents an aspect of your personality that is outrageously big or "over the top." Very powerful irrational thoughts or ideas that are well beyond anyone's ability to believe them logically. A sign that you need to be a lot more objective or realistic. Aggressively demanding that people take you seriously when they are resisting you.
Negatively, a gorilla may reflect a ridiculous need to be bigger or more powerful than someone else. Asserting yourself in ways that are noticeably overboard. A ridiculous need to be dominant to the point of embarrassing yourself. A need for control that may look stupid to others. Humiliating yourself demanding compliance or to be listened to. Childish attempts to overtly control others.
Example: A man once dreamed of gorilla in a business suit. In real life he was a conspiracy theorist who was writing a book about his theories. The gorilla in the business suit reflects how organized he is about the outrageous claims he was making.
Example 2: A man once dreamed of seeing a gorilla looking up at the sky with awe and wonder. In real life he had been looking up at the sky at night believing aliens were coming.
Example 3: A woman dreamed of a Gorilla speaking to her. In waking life she was aware of herself looking foolish to all her friends because of a very big public fight with her boyfriend that involved the police that made her feel that she embarrassed herself taking the fight too far.
