For some time now, I have been seeing the image of a dark lake in the back of my mind; a black lake, dark and smooth, against a backdrop of the images of my thoughts. It has been growing, sending out investigative arms, so that each time I picture it in my mind's eye, it is larger.
Tonight it occurred to me that its blackness didn't indicate presence (as of a fluid such a water or oil); rather, it indicates absence, the absence that is growing inside my mind; erasure.
