self aware, self conscious

(いしき) Consciousness, as in “I lost consciousness,” but also as in, “She’s environmentally conscious.” or “I hate those socially-conscious rock stars like Bono. Bono should perish.”  If you want to talk about a magic lamp or magic shoe-horn that is alive and has intelligence, use 意識.
 
てれる Self-conscious in the awkward teenage sense.
 
(じかくする) A more philosophical word than 意識. 自覚 is more like self-aware or enlightened. Or if you say 自覚的 it means subjective (as opposed to objective).   $$$
 
It seems like you can use both 意識 and 自覚 in the negative, to mean “did xxx without thinking”.
