There are three levels of awareness. A first level awareness is the subconscious level, where we are unaware of our surroundings.
This is also the first level of awareness that seems to be on autopilot. The second level of awareness is the conscious level where we notice what is around us. This is the level that we use to make decisions. A third level of awareness is the level where we actually control what is around us and can make decisions about what to do.
