If you are running late in a dream, ask yourself what deadline are you up against in real life. Is it work related? Or is it a self-imposed deadline? Is there something you are afraid you might miss out on? You are telling yourself through this dream to get your act together and focus!
Also ask yourself where in your life do you feel time is running out. What do you need to do before time runs out.
If you are trying to get pregnant in rel life, this could be a sign that you are pregnant!
