You might like to think about taking steps to become better in your job, so that your boss might appreciate you better. Going the other direction, you might consider looking for a new job with better prospects.
If you are not working because you’re jobless, then your dream continued your thoughts of your day. This dream is a reminder to continue job hunting and never give up.
