Illusion

It's 2.33 am and I'm still haven't sleep. I don't know, everthing just isn't seem what I thought it should be. I'm confused. I just realize that I'm living in a world where I judge things visually and through my logical analysis. For a moment I thought I knew everything, I thought I can forecast and foresee every action. Everything in my life was seems to be logically carried out, every action followed by a logical consequences, every question came with an answer. Everything seems to be so perfect. But for a moment, I thought I know nothing. Rules are being mended and broken, chaos taken in place of order, and action without logical consequence...

What is life? How do you define life? How can you be so sure you're living in a real world instead of a dream? Do you venture out of your paradigm to find out the real reason that things happens, or do you prefer staying in your comfort zone thinking everything happens for some reason that you've made up? Did you realize your life is confined to the knowledge you're having now?
