The truth of conciousness is that no one knows what it is or were to look for it. The brain physically responds the same to actual experience, as it does to imagined experience, but the conscious mind is aware of the difference between the actual and imagined. The consciousness is opperating seperate form the brain. Perception tells us that the concious mind resides in our heads, but we can not identify it's physical location.
This brings us to quantum physics. I don't pretend to know anything about quantum physics, but there is this question of were atomic particals are going as they move in and out of existence, as they constently do. finally there is the fact that the large majority of space is vacum, including all of matter. Apparently matter is not as solid as it seems. Most of the volume of matter is the vacum (space) between the particals (constently comeing in and out of existence, sometimes seeming to be in two places at one time) that make up it's mass. Is consciousness the living vacum residing within these biochemical masses of matter?
that which we are;
consciential (pertaining to the consciousness)
conscientiology (consciousness, science of); noetics; consciousness studies
projection of the consciousness (out-of-body experience)
altered state of consciousness (e.g. hypnagogic state)
