Your "professional life" is your job or career. In the example above, the speaker thinks that her friend dreaming about being on a sinking ship means that he is worried about his job.

People sometimes name different parts of their lives in this way. Here are some other "parts" of a person's life:

• Your personal life is what you do outside of work.
• Your home life is what happens at home with your family.
• Your spiritual life includes prayer, meditation, going to a church, temple, or mosque, and so on.
• Your romantic life is time that you spend dating, having sex, or talking to your husband/wife/boyfriend/girlfriend.
