wakefulness怎么记

Some dream episodes occur during what is known as "mixed-state sleep"-when the boundaries between wakefulness and sleep become fragmented, said Dr. Carlos H. Schenck, a psychiatrist and sleep expert at the University of Minnesota Medical School.

美国明尼苏达大学医学院（University of Minnesota Medical School）的精神病学家、睡眠专家卡洛斯·H·申克（Carlos H.Schenck）博士说，某些梦发生在所谓的“混合睡眠”，也就是俗话说的半睡半醒状态下。

This is the sort of mixed-up mental state I am familiar with from bouts of wakefulness at three in the morning.

这是我所熟悉的一种头脑不清的精神状态，在凌晨三点失眠时多次出现。

This does not mean, however, that happiness and optimism are no good, healthy wakefulness is undesirable, sweets of life are evil and hearty laughter is vicious.

这里并不是说愉快乐观是要不得的，清健的醒是不必求的，甜汤是罪恶的，狂笑是魔道的；
