You have not mentioned how the dream affected you emotionally, ie was it a good or bad dream.
Cats are very independent and self reliant creatures. If you were scared it means you are anxious about being independent etc.
Having children when you don't have any is usually your body clock trying to tell you things. If you were scared it is a sign of fear and insecurity. If you were not scared that you crave responsibility and this could be related to how other people see you. You want to give that impression so people will take you seriously.
