A dream that you are doing aerobics can be a message that you need to pay more attention to your physical health.
Are you getting enough exercise, eating a healthy diet and getting enough sleep?
Do you have any physical problems that you should see a doctor about?
You may dream that you are doing aerobics if you are full of energy that you are unable to release in waking life.
You may find yourself unable to fully express your happiness about something, or you may be repressing frustration or anger about something.
If you dream that you are in an aerobics class but are having trouble following the choreography, you may feel that you have been placed in a situation for which you are unprepared.
Dreaming that you are leading an aerobics class can mean that you want to control the actions of others.
