I have rarely had nightmares during my life. But when I'm on the worse end of the health spectrum, I tend to have an occasional very bad dream. I wake up really upset by what I was dreaming, and sometimes am scared to go back to bed. I have trouble talking and it's difficult to explain to family members what is going on. It seems to me that there is a huge physical component to this. What is it about this illness that makes this happen? Sometimes these occur when I'm more stressed, but not always. Sometimes it's just out of the blue. It would help if I could tell my family that this isn't all in my head.
