In A Second You Become Happy Or Unhappy

Why is it that in deep sleep you are not happy or unhappy? When we analyze it we find out that the mind is not there in deep sleep. But it has not left you because as soon as you wake up it is there. Then you are either happy or unhappy depending on what thoughts you are thinking. In meditation, you are freed from your thoughts and from your mind so in a second you are free. You are in a higher state of consciousness whereby you are not identified with your mind even if you are thinking those thoughts.
