Sleep anyone?...

Its three thirty and again I cant sleep. Retired to bed exhausted mind you, but sleep eludes me, I awoke of course after a dream. and a cat. The dream  was about  her,  not being able to fight, or even argue the toss, she was standing there in a white wedding dress, a changed person I guess, and I was asking why?, and then I dived into a life or death debate on how I loved her. It was soul destroying., and that's where the cat comes in, as during the night I have listened, as I do right now to its incessant wailing. It locked itself in my garage last night, and now prowls the garden , like some sort of mermaid, a siren if you like, a melancholy wailing from the depths of the deep Ocean, pricking my conscience, as if its trying to tell me something, but then there's nothing I can do now?. Why does her memory haunt me so....
