“It seemed like he had been falling for years.
FLY! a voice whispered in the darkness, but Bran did not know how to fly, so all he could do was fall …
The ground was so far below him he could barely make it out through the gray mists that whirled around him, but he could feel how fast he was falling, and he knew what was waiting for him down there.
Even in dreams, you could not fall forever.
He would wake up in the instant before he hit the ground, he knew. You always woke up in the instant before you hit the ground.
AND IF YOU DON’T? the voice asked.”
…. GEORGE R.R. MARTIN A Game of Thrones
