@sierrawoods, Welcome to the group and I hope someone has the solution to your riddle. When you wake up with this high adrenaline, do you have any other physical symptoms? The reason for the question is that I awake feeling as if everything inside my body is vibrating. Yea, I know that is weird, but I can not find any other way to describe it. The best answer I have found in researching is that I am have a panic attack in my sleep. I have no dreams, or at least any remembrance of them. I do not understand how this is possible, but that is the best answer I have found. It is a bit disconcerting, but not really painful, just strange. If you find your answer, I will be very interested in what you learn. Would someone please try to help Sierra find an answer or point in that direction?
