Well, the third eye chakra is not the one governing higher conscious or awareness. Or altered conscious for that matter.
Also you need not bother fretting over "opening" your chakras. How do you open a door that's open?
And you don't necessarily need to worry about using your chakras for the sake of controlling energy and for spiritual/ethereal awareness. It's rather subjective. If chakra work is your thing, good for you. If it's not your bag, then good for you too. Many systems and practices that deal with energy, spirit, higher awareness and consciousness, etc., don't acknowledge the chakra system. And they get by just fine without it.
Point is, decide if it's what you want to do, study it, and work with your chakras equally and in harmony and balance, if you so choose to do so.
