Transitional forms occur in the human brain:

Human awareness occurs as a gradual state, ranging from focal awareness (that which we are most focused on and acutely aware of)

down to fuzzier awareness (things that are on the tip of the tongue, peripheral vision)

deeper down to the murky depths of the subconscious (dreams and nightmares),

and then deeper still to the basic limbic level, the level which regulates breathing and the autonomic nervous sytem and heartbeat.

We are always constantly conscious on many different levels.

The study of the physiology of the human brain is fascinating, because you learn that the human creature is a mind-bending mix of different:

brain halves (right brain, which is abstraction, and left brain, which is analytical and ordered),

lobes (Wernicke's Area, which allows you to comprehend language, and Broca's expressive area, which deals with speech production, and many others)



and then there's the:

limbic system
(the primitive part of the brain which deals with base instincts, and which is the most animal-like)
vs.
the neocortex
(the most recent part of the human brain, which allows for detached awareness and abstraction and advanced intelligence and science....)
