Hearses are associated with death, and death in dreams often represents change, so if you dream about a hearse, you could be going through an important change in your life.
A dream that you are driving a hearse to a funeral can be a message that you have to rid yourself of old behaviors and old ways of thinking.
If you are waiting for a hearse but it never shows up, you might not be ready for change.
If you dream about a hearse, it can mean that you are afraid that you do not have enough time for something.
You could be thinking about your own mortality and be worried that you do not have enough years left to do all of the things that you wanted to do during your lifetime.
However, you could also feel that you do not have enough time to complete a project or to reach a goal that you have set for yourself.
