Omega - I used to remember three a day or more dreams. But now I only remember one every few weeks. But there are two types of dreaming, the REM dream which is full of images and scenes, and the NREM dream which has no images, but is experienced as long thoughts without images.
I experience these a great deal now. Maybe you are experiencing these type of dream, or your unconscious is summing up and doesn't need to press on yet, perhaps because it/you have work to do inside?
I'm guessing.
