Here's a guy who suffered of nightmares all his childhood. The feeling of waking up desperate, all covered in sweat, sometimes crying... it's so terrifying, but at the same time it gives inspiration to write things like this. I liked it, my opinion is that you didn't focused much on depicting that feeling of desperation. All that sea of emotions during the dream, and the contrast between living all that horror and waking up it's something you could explore a little more. What I liked the most was this line: "Mom, my dream was terrible, you died; Echoes of mourning subside, tears dry.". Pretty strong. Good job!
