Moksha

Moksha isn't cessation of dreaming. Rather its a stage where we accept that every phenomena (dharma) in existence is impermanent (anicca/anitya) and devoid of self-existence (anatta/anatma). Suffering comes when we grasp onto these dharmas as being permanent, and thus we are unable to accept that things change. 

Suffering itself is of three types - suffering of suffering (dukkha dukhhata), suffering of change (viparinama dukkhata) and suffering from mental condition (samskara dukkhata).

In moksha, mind stays calm and uniform, not overly thinking, overly feeling, overly grasping, a perfect state of equanimity (upekkha/upeksha).
