Flow Experience: Discovered by the psychologist Mihalyi Csikszentmihalyi, who defined it as flowing experience where the self reaches undreamed levels of consciousness and an evolved level of self-hood.
It can also mean a high level of attentive arousal during touch and go situations (e.g. rock climbing, auto racing) where you'll likely lose your head along with your self and your consciousness if you don't pay attention.
