Fear in a dream typically represents what anxiety might continuously be associated with, how we perceive ourselves under the present circumstances, or how it ties into our waking thoughts.
Dreaming about fear signifies anger and abuse transferred though subconsciously to the dreamer. The fears of losing control over power are attached with most people’s dreams of their future selves becoming weak or powerless which turns into a warning or a major trigger for a self-discovery phase where you should look back on your life in order to make necessary changes from there in your waking hours.
Also, fear in a dream could stem from sudden success, new situations, enemies/threats, children, and unexpected social interactions.
