The Sensory Realm.
I am convinced that sensory perception is it's own dimension of reality. I think subjective phenomenology is not generated by the brain but conjured by it. I think it comes from somewhere outside time and space. It really can't be explained in terms of the 4 basic dimensions.. Experiential subjectivity is a very strange phenomena. I would say perception might even be it's own dimension of reality. The five senses may even be dimensions unto their selves, as they're so different from one another. Each primary color may even be a separate dimension.
