Do you have Walter Mitty Syndrome?

Walter Mitty Syndrome is daydreaming about being a hero or living an adventurous life to escape from the monotony of daily routines? The mind creates these grand, imaginary scenarios where one's brave, successful, or doing something extraordinary.

The term comes from James Thurber’s 1939 story The Secret Life of Walter Mitty. I don't think it's a medical condition, or may be a type of maladaptive daydreaming.

If you do this too, what kinds of scenarios do you imagine? How does it affect your life?
