I'm assuming by your series of labor questions that you are expecting.
That being said it is perfectly natural for a woman to have fears of not being able to get the hospital on time, or their loved ones not being there on time, etc. (my wife had dreams that we brought our baby home and none of her clothes fit) These fears be it rational or irrational are manifesting themselves in your dreams. The best thing you can do as an expecting mother is to calm yourself down. Stress is a very powerful thing and can have negative effects to both yourself and your baby.
