David - I don't have PD but my loved one does. However, I have such vivid dreams, I am almost certain they actually happened. I also am easily startled. When the phone rings, I jump out of my skin. Sometimes when I am writing, my hand suddenly jerks upward, or downward, and of course my pen follows. I, too, have problems with memory. Sometimes, when I get up in the morning, I'm not sure of the day or the date, and I have to look at the newspaper. In MY case, it's called stress, and WORRY. My mind is so filled with "what if's", that I have a hard time thinking about "what is". Please don't think I'm saying that this is true in your case, but I did want you to see how a Non-PD can react much the same way. Hope you get a diagnosis soon. Even if it's "for" or '"against", at least you'll know where to go from there. Best wishes . Jo Ann from Houstoni
