To dream of being unemployed or jobless represents feelings about yourself not having anything important to do. Feeling inadequate or that you are not good enough or aren't needed. It may also reflected feelings of being stagnated in life or having low self-worth. Feeling that you are not being utilized to your fullest potential.
Alternatively, being unemployed may reflect feelings of having lost a sense of responsibility or obligation for something in your life. Examples may be kids growing up and not needing you, technology removing the need for a chore to be done, or friends no longer needing you to do something for them.
