Why does my stomach ache when I have a certain dreams? (Most of my dreams are not nightmares but regular dreams and I would wake up and my stomach would hurt I would get up move around lay down again, for maybe a minute and the dream would come back and my stomach would hurt again. So it would keep me up, one way to make my stomach stop aching is by doing something and forget the pain, but sometimes it would come back even If I was doing something. I need help with this problem)
