To me consciousness is very simple. It is simply us observing our brain at work. We can can experience light, that is how we observe many processes in the external world. But what we really experience is some changes going on in the neurons in our brains. Then we can also experience sounds and touch etc. That means we can experience and observe our own neural activity. Consciousness is the "sixth sense" that allows us to experience what is going on in some specific parts of our brain with which we "observe our brain's observation activity". (So to be clear I'm not talking about any paranormal sense. If that exists it is the 7th sense. Consciousness is the 6th)
