Dreams

On the first night of my ovulation cycle, after me and husband had some fun I had the strangest, happiest, most exciting dream ever. But when I woke up I also wanted to cry. Cause it had to end. I had a dream I gave birth to a baby boy. Then in the dream when we came home we had a little girl about five years old waiting for us. Can dreams be a sign that we finally succeeded? Or is just my mind messing with me because I want it so much and we have been trying for so long? I really hope it means we have finally had some luck. What do you guys think? Am I just going crazy? Or can it actually mean something? Have any of you had something like this happen to you?
