On a walk to the store the other day I came up with 11 states of consciousness we know exist in the Universe:

Mineral (rocks, water etc.) - purely material, no true individual existence
Chemical (stars, nuclear bombs, etc.) - has a basic system, but still only a little more complex than a rock
Fungal (mushrooms, etc.) - least complex form of life, draws nutrients directly from a living or nonliving source
Vegetative (plants, sponges, totally comatose humans) - The lowest state of consciousness a human can experience. Exists in plants and in simple and highly incapacitated animals
Mobile (simple animals, ie bugs, fish, etc) - An important step in the evolution of consciousness on Earth; most mobile animals have nervous systems
Limbic (reptiles, frogs, etc) - The first emotional consciousness level. Fear, rage, and contentment exist in limbic beings, but not more complex emotions.
Melancholic (mammals, birds) - Common to more complex animals, including humans.
Intellectual (humans, primates, whales, dolphins, elephants) - Conscious enough to reflect on why they exist.
Spiritual (humans, perhaps a few other species) - Has some sort of belief we are all one. I feel most humans are more Melancholic than truly Spiritual or Intellectual, but most of us are a bit of all three.
Buddhal (Buddha, Jesus, prophets etc.) - Has "seen the light", gets what the Universe is about. Few of us have ever reached this level.
God - Interconnectedness.
