Specifically, do you imagine yourself in particular situations where you're better off in some way than you are now?
If so, I'd like to know what you visualise. Some people simply don't day dream I know, so fair enough if that's you. As a good man once said:
"You can dream a little dream or you can live a little dream - I'd rather live it, 'cause dreamers only chase and never get it."
Answer accordingly. You are allowed to elaborate.
