|Well, I think it was pretty darn good...lol. Sure it's got some rough spots, but nothing drastic. You have described a man's fear in a very chilling manner. This is what I would do with this middle part:
I shot up out of bed, my breathing going a mile a minute. Sweat flooded down my body, soaking my clothes and my sheets. My face was red, and my head was pounding. It was still dark though.[this last sentence doesn't fit this paragraph. Or you could make it the 2nd sentence in the paragraph. It would fit well there.]
I junped out of bed[you got out of bed again?] and turned on the lights, illuminating all of the dark corners. I assured myself it was all a dream, all just a bad dream. I sighed and looked at my digital clock flashing numbers: 1:37. I let out an exasperated breath and tried to go back to bed. It didn't work, so I got up [again you get up?]and went to the kitchen to get something to eat, or at least to do something.
Other than that it was very frightfully done. It's better writing than I see from most of the adults on this site...lol. Best wishes with this,
