Consciousness and awareness are two different things; just as perception is not the same as consciousness. Consciousness is also often confused with sentience. Sentience is the capacity to be aware of feelings and sensations. Sentience and awareness we share with the animal world, consciousness is not available to animals as it requires sort of a ‘double take’, a ‘thought about thought’ modus and may even require language to develop and exchange concepts.
In Scientology consciousness is adequately described in the concepts of the thetan, the analytical mind and awareness of awareness unit. Awareness is mostly perceptual experience, it  exists in many forms such as sense perceptions, the experience of art, in meditation and Buddhist mindfulness. Percepts depend on the concepts of space and time, as without those one cannot hear or see. Consciousness requires concepts and thought about concepts, even hierarchies of concepts, it’s meta-awareness. It’s also referred to as apperception, in more scientific or philosophical circles.

Hubbard in Scientology, often fails to distinguish between these two concepts and defines consciousness as awareness and awareness as perception:

CONSCIOUSNESS,
1. awareness of now. (DTOT, p.24)

2. consciousness is awareness. Awareness itself is perception. (2ACC-8B, 5311CM24)

AWARENESS

1. the ability to perceive the existence of (HCOB 4 January 1973)

2. awareness itself is perception (2ACC-8B 5311CM24)
