They're supposed to be a recollection of the mind, where it sorts out what had happened, and your dream is a mindscrew of things that happened to you mashed together, right?
Nightmares, though. They leave you awake with your heart pounding, and a cold sweat covering your body as you try to recollect what just happened. Sometimes you can, but most of the time the fragments slip through your fingers and you're left wondering what left you shaken up so badly.
Then there's always that one horror that's created in the depths of your brain. It haunts you. It keeps it's claws around you throat, waiting for the chance you make the wrong move, and pop, you're dead. Insecurity. Fear. Terror. Guilt. Sorrow. Shame. It feeds on negative feelings, growing stronger while you're just trying not to screw up in life.
Dreams can be horrifying. Yet there's the good ones to. The ones that make you not want to ever wake up. The ones that make you think that you don't suck and you actually belong somewhere. It's paradise. But it's just a tease, because eventually you will wake up, and whatever you dreamed will just float away into borderline nonexistence, buried somewhere in the dark gallows of the brain. Lost forever, until it suddenly decides to pop back up again. And again. And again. Every time you think you're closer to achieving something it's yanked away from you at last second.
Yet people need to sleep. If you don't, you die. It's not fair, is it? Either die or be teased while you're able to live.
Now, take me. I can't remember anything. How do I sort the shards of what I can recollect together? I can't.
But the answer's hidden in there somewhere...
And you wonder why people say "life sucks".
