You operate at a normal state of consciousness. Sometimes, things happen in your life that plunge you into what is called an "altered state", a state of mind that differs drastically from your normal state of consciousness. This altered state can be induced by drugs and alcohol. But, it can also happen when you're hungry, under the weather, in the throes of love, filled with rage, running on very little sleep or under extreme amounts of stress. What's important is that you're fully aware of the moments you're in an altered state and operating outside your normal state of consciousness. Through this awareness, you can remind yourself to take a step back and observe (rather than act) while your mind, body and heart stabilize.
