Lucid Dreams

15 In a dream, in a vision of the night, when deep sleep falleth upon men, in slumberings upon the bed;

16 Then he openeth the ears of men, and sealeth their instruction,
17 That he may withdraw man from his purpose, and hide pride from man.
18 He keepeth back his soul from the pit, and his life from perishing by the sword.

[Job xxxiii (King James Version)]
