What does it mean when you keep dreaming of someone else being sick?

Dreams communicate through symbols, and it is not unusual for you to be represented by another person in a dream. For example, if you have a broken arm, you might see someone else with a broken arm in your dreams. It can also mean that there is a problem is a specific area of your life. Perhaps you dream of a truck driver being sick. That might suggest that you have a problem with your driving. Seeing a schoolteacher sick could mean you have a problem at school that needs attention.
