There exists so many 'oddest things' in this world. This fact isn't really one of them: it's just odd.
The less I sleep, the more hyper I get. When I sleep eight hours, the next day is pain. Utter pain. I cannot really engage in anything and hate every commotion around me. At five hours, I'm just sleepy. It sucks, it's unbearable, but, well, it's not giving me any misanthropic fancies or making me want to kill the outrageously funny person next to me merely for making me want to laugh when I cannot. Then, two-three hours, that's bliss. I'm super, thanks for asking, as the far too catchy song goes. I run around! I hop! I trip and behave like I'm high (and, judging by the amount of chocolate I consume and some of the ingredients in it, maybe I am). All in all, I'm perhaps rather annoying. Anyways, praying to Haruhi or reading something weird, or just slacking of to anime, can work as an postactive detractor of sleep.
