Reoccurring Dreams

I don't dream much or at least I don't remember my dreams. The few times in my life that I can remember dreaming are when I have had reoccurring dreams. The first time I ever had a dream that I remembered was when I started having nightmares after my grandmother died. I was in 3rd grade, I believe and it was a horrible time for my family. I had a few cousins the same age as me and when our grandmother died one of them just quit walking. I can remember them saying that it was psychological but I didn't understand that. I kept having nightmares about Mamaw coming to take away our ability to walk. It was very traumatic for me but in a few weeks the dreams went away and I would beg for them to come back just so I could see her again and remember what she looked like. The only other time I can remember dreaming is when I was pregnant with each of the kids and while each kid got their own dream it was the same dream the whole time I was pregnant. I don't really remember much about the dream I had with each of the boys now, they weren't really strange just normal baby dreams. The one I had while pregnant with Audrey though I will never forget. We kind of figured it was a news story or something that I had seen that had started it. I would dream that we were all at the hospital and I had given birth except it ended up being twins and one of the babies was black. I would keep asking people "Don't you think he looks different?" and they would just say something about how he looked perfect to them. I dreamed this over and over and over again while I was pregnant with her and it drove me crazy. I'm not sure if I don't dream often or if I only remember the ones that keep reoccurring but these are the only times in my life that I can remember actually having a dream. Obviously they were brought on by stress but it still seems weird to me.
