Hello, I believe I am a sleepwalker. I wake up sometimes in the middle of the night with bruises on my body and my heart beating rapidly. This happens when I have nightmares of trying to get away from something or to free myself from some form of imprisonment. There s a number of occurrences whereby I would actually walk to my front door and open it. As soon as I do, I wake up breathing heavily with my heart racing. Currently, I feel a slight tightness on the upper left side of my chest and the upper part of my left arm feels slightly sore/weak. Do you believe this could be the onset of a heart attack? Also, do you believe I should see a sleep therapist for my nightmares and sleepwalking issues? It s such a super crazy occurrence/issue for me that I am very bashful/embarrassed to discuss it. Please let me know what you think? SB
