 Phenomenal consciousness is the felt, subjective, or “what it’s like” aspect of mental states (see Nagel 1974). Paradigmatic examples of phenomenal states include perceptual experiences, pains, emotional feelings, episodes of mental imagery, and cognitive experiences such as the experience of déjà vu. Each of these states has a characteristic phenomenal character—there is something that it’s like to be in it. When there is something that it is like for a subject, we can say that she instantiates a phenomenal property, or that she has a phenomenal state. (See the entry  Consciousness.)
