A man sleepwalks off of a high cliff by the ocean dreaming he is walking a tightrope to the top of a volcano in the middle of the sea.

He makes it three miles out – the whole time in midair without a wire or support – and does not start to fall until he is blown awake by the wind.

He has the presence of mind to think “I’ll be fine if can dream of falling upwards,” and closes his eyes to fall asleep.

Seconds later his eyes open wide in panic when he remembers that he is an insomniac – a thought which seals his fate.

And so are we limited by the labels we believe.
