JK, That is horrible! I do have dreams also. Most of them are always ok! When I've had a Lyme/Fibromyalgia episode they can also wake me up with my heart pounding! Freud did a lot of research on dreams and what they mean! Psychology classes in college but I forgot it all!
Someone else may be able to lend in about where the people come back from our past?
