I used to see my sleep as a vital part of my life, the way I recovered the strength and energy for happiness. Anything that woke me I saw as the ultimate evil and would get angry as hell. One night the neighbor's dog lit off and wouldn't stop barking and I opened the window and started screaming curses at the neighbor that he's better get his ass outside and shut up his stinking dog.
It was one of the best things I ever did. I saw right there that I was insane. From that moment on my life and sleep turned upside down. From that time on I could care less if I can't sleep or if anything wakens me. And now I can sleep anywhere and any time or not and it makes no difference. Whatever is is and it's fine just like that. I never cared at all, it was just my ego who felt he was too important not to be able to sleep when he felt he should.
