Deep sleep
A sleep so complete the dreamer is not aware of it — the body's full retreat into restoration.
Deep sleep in a dream is the dream's image of the body's full retreat into restoration. Deep sleep is not the sleep with dreams; it is the sleep below dreams. The dream brings deep sleep when something in your life — an exhaustion, a recovery, a long stretch of depleting work — is being met by the body taking the rest it actually requires rather than the rest the schedule had allocated. Deep sleep entered without struggle is the dream affirming the honest acceptance of the body's need. Deep sleep refused, with the body kept in the shallow waking state by anxiety, is the dream noting that the recovery the body was going to take has been blocked, and the depletion is continuing to compound.
