Methought I heard a voice cry ‘Sleep no more!
Macbeth does murder sleep’, the innocent sleep,
Sleep that knits up the ravell’d sleeve of care,
The death of each day’s life, sore labour’s bath,
Balm of hurt minds, great nature’s second course,
Chief nourisher in life’s feast,–
Macbeth Act II
To be, or not to be, that is the question:
Whether ’tis Nobler in the mind to suffer
The Slings and Arrows of outrageous Fortune,
Or to take Arms against a Sea of troubles,
And by opposing end them: to die, to sleep
Hamlet Act III
The Doctor and Clara land on a space station in the 38th century, and face the thing nightmares are made of: sleep.
Okay, that sounded corny. But, it is Doctor Who. Corny sometimes happens.
It’s the first true solo episode of the season, and, if we believe what we saw, the Doctor lost the battle.
