I'm not really sure what to do about this. My first thought was to see a therapist but I don't have the money.
I have constant nightmares that are causing me physical pain/problems when I wake up. One of my earlier problems was, and probably still is, teeth grinding. I haven't been into the dentist for a couple of years, but the last time I went my dentist was telling me about a receding gum line (if I remember correctly) and that it would mean the loss of certain teeth if I didn't stop grinding my teeth. I told him that I don't grind my teeth, but his next question was do I have nightmares because that may be a cause for it in my sleep. I do have nightmares and do often wake up with sore teeth, sometimes clenched tightly.
My more recent problems involve muscle pains throughout my body. My back, neck, arm, or chest muscles can be extremely sore or have sharp pain upon waking. These can be quite severe at times, sometimes my neck muscles hurt so badly that I can't turn my head a certain way for hours after waking. Just in the last couple weeks I've been getting what feels like heart pain on the left/central part of my chest. It is very sharp pain that becomes worse with deep breaths, but it's difficult to avoid deep breaths because my heart rate increases to such a high speed when it happens. Sometimes it is so bad that I can't walk around my apartment and will have to sit still for around 30 minutes or longer waiting for it to subside to a smaller level. The way this pain starts has usually been a sore feeling in the back and chest region (left/central part of the chest and back) upon waking, it then will become a sharp pain out of nowhere (usually sometime around noon) which forces me to immediately stop whatever I'm doing (which has usually been getting out of the shower or organizing my school papers) and sit down.
I'm pretty sure solving my nightmares is what is necessary to solve my other problems but I figured I'd include a detailed description of the chest pain because it worries me so much. Is there any way to stop these nightmares or somehow protect my body from the inflicted stress at night? Any insight would be helpful.
