Something wrong with me?... -UPDATE-

So, I was awoken in the middle of a night sleep by Mom, then she told me if I was dreaming of anything, which I didn't. But she heard me murmuring that many characters were there and I was cracking knuckles in sleep.

But I never got any sense of those in mind. nor do I have any idea if all of that happened.

... Is there a hidden side of me?

What's wrong with me?

EDIT: So, turned out that it was my subconscious acting up, and I found this while searching on Wikipedia:
With stress, drug and alcohol consumption has also been linked to sleep walking activity. Though alcohol is a sedative, and usually puts a person to sleep, the quality of sleep they undergo is usually not ideal. Alcohol also tends to increase the number of times the sleeper wakes. Not only is the sleep quality an issue, but with alcohol and the risk of getting up and sleep walking, there is the additional problem with intoxication, which is increased clumsiness. With increased clumsiness comes increased danger for the sleep walker to fall into things or fall down stairs, etc.

... I guess alcohol was the cause of this.

Uh, I'll never drink again.. First try with my parents around? Yeah, good at first, but now? Scary.</span>
