'Multiple states of human consciousness'

Research suggests there are states of arousal that fall between conventionally categorized states such as sleep and waking, supporting [John Lilly's] intuition that there are multiple states of human consciousness we have yet to fully explore. In the 1990s, the discovery of the Default Mode Network, an interconnected archipelago of brain areas whose activity decreases when we are focused on a task and increases when we stop focusing, complicated the notion that brain areas are either “on” or “off,” in use or on hold.
