One image that constantly comes to my mind as a prelude to thinking of my own images is also a horse image. Its one of Keith Carters images and one of the images that sucked me into the analog world of photography like a spider sucked up by a vacuum hose. His images, like Susan B's images, are like photographs of actual memories, which is very much like what you said Karl, "I am wondering if there is anything in this, a prologue to the notion of photographing your dreams."
There is something very intriguing about the idea of making memories of memories. I mean, I always looked at photographs as a way of capturing a memory outside of the mind. A memory you can touch and hold in your hand. So when a photographic artist makes a photograph that to me looks like a memory in my head, I really wonder what that artist has actually created and if it goes beyond simply calling the work "art."
But then the idea doesnt stop there because I realize that some peoples memories are probably crystal clear, with no blur at all, and that the artists that create crystal clear images must also be creating memories of memories. And I wonder if we arent filling the world up with tangible memories. And then this all starts to get really deep and reminds a lot of Sontags writing about photography and her photographic world becoming more real than the world we all think is real. I really hated her book after a while and some of the ideas she presents are really insulting to photographers, but I havent been able to let go of some of her ideas.
Anyway, I could go on forever about this. The images that come to my mind as I drift off to sleep are often images I want to create of the landscape around me. Funny thing is, the images are all so different in my head because of all the different kinds of film cameras I have. LOL!!!
