“The first time...' the Doctor said, snapping Chris out of his reverie, 'I don't remember, I was unconscious. The second time...I don't want to talk about.'

The third time?'

Unconscious.'

The fourth time?'

Atypical. There were some strange time and energy effects involved.'

But, you know, what does it feel like? Is it good or bad?'

Good,' said the Doctor, 'in the same way that driving a vehicle very, very fast is a good feeling, until pow!' He slapped his hands together suddenly. 'Like being shoved through a window. That's what it was like the fifth time.'

What about the sixth time?'

Unconscious.”
