dehydration.

is it possible to forget something that really bothers you?
have you ever had a secret that you are even afraid of telling to yourself?
and have you ever told this vast information to someone who is the most irrelevant both to you and to the subject. do you see this person around a lot? if no, you may think that it is not a big deal, you might not see them for sometime and totally forgot that you told them, but the second you bump up to them, the second it is a Damn-big deal. this encounter, at first will seem to you as just a coincidence but the moment you understand that it is not, this thought makes you want to puke. or even makes you go puke, not kiddin, you just leave the place and throw-up in the middle of the first deserted road you find. it is not finished. did you think you can get away with just emptying your guts? of course not, you wont be able to sleep nor think about anything else but just the fear of the secret to be spread.

yeah if you have experienced or think that you can experience half of the things that has been just narrated, you may diagnose yourself as paranoiac.
get over yourself and go to sleep.
