Waning Energy, Boredom Calls

It seems lately, no matter how much I sleep, I'm still tired. The more I sleep the more tired I am, and the more I am haunted by unusual, and sometimes unpleasant dreams. I often wake up with a start, not qite remembering where I am before I close my eyes and am reclaimed once more by my dreams. Covered in sweat and actually fearful for once, but not knowing why. It seems they inhabit my daily life, too. I've seen the pale figure, wrapped in black cloth and chains at almost every moment. I look, but when I glance its way it disappears leaving only a quick chill breeze, the rustle of cloth, and I am quite sure...a mocking laugh. If it is real then it haunts me, following me with every breath. If it is not, then I guess I'm either crazy or something has crawled into my brain and died, leaving its stain there to taint my mind. But it seems that the sleep or lack of, whatever it may be, is my main problem. I've gotten back into the bad habit of sleeping through my classes, though I do manage to keep up. Although the vitamins I have been taking had been helping, it seems they no longer work. I think I may blame this on the new perscription my doctor gave me, for instead of relieving my pain, as it should, it adds to it greatly and often leaves me weeping. So, if it does the opposite of what it is supposed to do, why couldn't it cancel out the affects of the vitamins? I don't know, I just want to solve this and hopefully get my peaceful slumbers back. Until then, I'll have to deal with it, and the chained figure, if it has to do with the sleep at all.
