REM cycle mysteries

I am not one to have reoccuring dreams, but I do have reoccuring themes. Like the dream I had last night... In many of my dreams I have a child, and of course not a normal child, they are always a strange size or age, depending on the situation. Such as, one night I had a dream that I birthed a 3-year-old child, it basically just walked right out of me, and instead of giving it a name, I was able to ask it what it wanted to be called, in which it replied, Meagan ( I know, perverse). But last night, my child was definitely smaller than normal, and as the dream went on it became smaller and smaller. By the end of the dream it looked like a popsicle stick with a head. Then I lost it in Wal-Mart, but luckily someone found her/him, and we had a long conversation about how we hate the "stick stage." What do these dreams mean? Why can't I have normal running down the street naked dreams? Why?!?
