The dream may be a metaphor for feeling powerless or overwhelmed. It could represent feelings of being trapped or unable to escape a difficult situation or the dream may be symbolic of feeling embarrassed or ashamed, feelings of being unable to cope with stress or anxiety.
Alternatively, the dream could be a warning about not being able to meet your own personal or professional expectations.
This is my interpretation of what it means to not be able to run in a dream. At times, the best interpreter of a dream is the person who had the dream. Always keep your own life and nuances in mind when trying to determine what you think a dream might mean, or if it meant anything at all.
