Nightmares and Vertigo

Why do I have vertigo? It happens only rarely and is much milder than when it originated, but still why do I have it?
-a concussion or two? or three?
-electrolyte imbalance?
-mild Mineire's?
It also seems to be coupled with a growing fear of heights. Riding an escalator or going down stairs that are high off the ground and exposed on either side give me the willies and set of my internal panic mode. This is in no way debilitating but at this stage just annoying!! Normally breathing and focusing and making a joke about it and I am good. But that fact that I even sense this bugs the crap out of me.

And of course as you have read about here often, my freaking nightmare issue. They say you can't die in your dreams. Well I am here to tell you that is a lie. I have been murdered, died and committed suicide to total completion in my dreams. I don't wake up before hand, I wake up after screaming, panting, sweaty and thrashing around in the bed.
I don't watch scary movies, I don't listen to sad music, I am not morose by nature. I have a life others consider amazingly easy. This may not have been true my whole life, but it is now.
So why the horrid, vivid continual nightmares?
-concussions?
-a big of undigested potato?
-having a chronic illness?
-too many high fevers?
-being in Iraq?
-I'm psycho?

I rarely get a cold or cough. I am totally immune to strep it seems. It takes a lot to bruise me. I can't think of the last time I was sick in any way that didn't relate to my guts.

But yet I have these chinks in my armor that are driving me more and more crazy. So if you wanted to know my kryptonite then here you go. I get vertigo sometimes, especially related to heights. I have horrible nightmares that make sleeping unpleasant. And my connective tissue (tendons and ligaments) seems easily damaged.

Taking my own words to heart though, 'action is the best response to misfortune' and trying to have an attitude to gratitude I will still be thankful for what I do have and where I am strong.

Thank you God, for everything.
