habitual timer

Do u believe that human have it's own timer. obviously, for example hungry time, thirsty time, sleepy time, etc. that timer maybe exposure of the unconciuse mind, buat also it's habitual or even a very strongfull desire. i have made my own experiment with atleast 20 of my pals. there's a mp3 player within 1 hours duration list of song. the structure of the song is my pals type, even my pals vote it by hemself. and the experimen begun, i type it. the song that my pals where sleep is muse with unintended. and the next one hour, my pals woke up also at muse unintented. this make me think that habitual and desire make it's own gain and play.
