A Connection Experience (a.k.a. Connection Event, CE) is a temporary, sometimes abrupt and dramatic, increase of Consciousness (measured by CQ (Consciousness Quotient) sufficiently above one's average daily CQ as to be perceived, by the individual, as a qualitatively different state of awareness/consciousness/being.
The Q-Scale may be used to estimate the intensity and quality of a connection event.
Connection experiences may be understood neurologically, as what occurs when the Default Mode Network (otherwise known as the Bodily Ego of the individual's brain releases control and allows Consciousness to flow into the Physical Unit (Sosteric, SOA1). Release may occur naturally, under conditions of aligned safety, or it can be forced by exploiting powerful Connection Supplements.
