People can know that organisms, oneself, objects, features, times, or locations are present {awareness}|. Awareness is about currently observed time and space, including imagined things. It is not about too far away, too small, too large, or completely unknowable things, such as gods or spirits. Awareness is not about past or future, memories or imagination [Baddeley and Weiskrantz, 1993] [Block, 1995] [Block et al., 1997] [Chalmers, 1993] [Chalmers, 1996] [Chalmers, 2000] [Chalmers, 2002] [Lamme, 2003] [Metzinger, 1995] [Tulving and Craik, 2000] [Tulving, 1993].
levels
Coma and vegetative state have no awareness. Anesthesia, deep sleep, and minimally conscious state have low awareness. REM sleep, dreaming, stupor or drowsiness, and awakeness have high awareness.
types
Awareness of perceptions, moods, emotions, or feelings {direct awareness} is transparent to mode. Awareness of properties, relations, statements, or situations {propositional awareness} is opaque to mode, because it depends on concept information [Dretske, 1995].
biology
Thalamocortical activity depends on meaningful-stimulation intensity and determines awareness level. Cortico-striatopallidal-thalamocortical loops underlie awareness. Perhaps, all mammals can have awareness.
meaning
Awareness is not about meaning and so differs from experience.
