Sleep is withdrawing; waking is joining.

Dreams are illusions of joining, because they reflect the ego's distorted notions about what joining is.

Yet the Holy Spirit, too, has use for sleep, and can use dreams on behalf of waking if you will let Him.

How you wake is the sign of how you have used sleep. To whom did you give it?
 
Under which teacher did you place it? Whenever you wake dispiritedly, it was not given to the Holy Spirit.
 
Only when you awaken joyously have you utilized sleep according to His purpose.
 
You can indeed be "drugged" by sleep, if you have misused it on behalf of sickness.
 
Sleep is no more a form of death than death is a form of unconsciousness. Complete unconsciousness is impossible.
 
You can rest in peace only because you are awake.
