Definition of slep

(Nathan Rapport, ""I've Been Here before!"...)

A `` mental_image '' subconsciously impressing us from beneath its language symbols in wakeful thought , or consciously in light sleep , is actually not an image at_all but is comprised of realities , viewed not in the concurrent sensory stream , but within the depths of the fourth_dimension .

When consciousness deserts the sleeping body and the wakeful world , it continues in the myriad progressions of the ever-present past and future , in a life as vibrant and real as the one left when the body tired and required sleep .

(B. J. D. Meeuse, The Story of Pollination....)

If we manage to keep track of a Bombus queen after she has left her feeding place , we may discover the snug little hideout which she has fixed_up for herself when she woke_up from her winter sleep .

(E. Gellhorn, "Prolegomena to a theory of the emotions"...)

Before we comment further on these pathological conditions , we should remember that changes in the state of the hypothalamus within physiological limits distinguish sleep from wakefulness .

Thus , a low intensity of hypothalamic cortical discharges prevails in sleep and a high one during wakefulness , resulting in synchronous EEG potentials in the former and asynchrony in the latter condition .
