I always have vivid dreams, to the point where it feels so real, like a world on its own. Sometimes it even affects the waking reality. I once dreamt of doing one arm chin ups, and ended up having sore muscles on the right half of my body for 4 days. The next time I sleep in on the weekends, my excuse shall be 'Exercising la!'

I really wonder what goes on inside that my brain when I sleep. It causes me bruxism where I grind and clench my teeth at night. My orthodontist says I am his number 1 grinder, he has many many patients by the way.

Maybe its the Matrix...
