Here are a few quotes from a book I recently read, "The Shapeless Unease  A Year of Not Sleeping," by Samantha Harvey.

Everything is holy. It’s only when we die that the holiness is called up. But it was always holy, all along.

An article explains how fear and anxiety, often conflated, belong to different parts of the amygdala – fear arises in its central nucleus, which is responsible for sending messages to the body to prepare a short-term response – run, freeze, fight – whereas anxiety arises in the area responsible for emotions, a part which affects longer-term behavioural change. Fear is a response to a threat, anxiety a response to a perceived threat – the difference between preparing to escape a saber-tooth tiger that is here and now in front of you (because it’s always saber-tooth tigers in the examples) and preparing to escape the idea of a saber-tooth tiger in case one appears around the next bend. While fear will quickly resolve – you will run away, fight it or be eaten – anxiety has no such resolution. You will need to stand guard in case, in case. Forever in case. Standing guard will make the perceived threat seem more real, which necessitates a more vigilant standing guard. Fear ends when the threat is gone, while anxiety, operating in a hall of mirrors, self-perpetuates. As a friend once said to me: there is no grace for the imagination. You cannot be saved from an assailant that doesn’t exist. 

For me, now, a puzzle emerges. What, then, fuels insomnia – fear or anxiety? Anxiety, everyone says. Anxiety, my hypnotherapist says; you are safe in your bed yet your heart is racing as if a tiger is present. You must learn to see that there is no tiger. 

But there is a tiger: sleep deprivation. Sleep deprivation isn’t a perceived threat but a real one, like thirst or starvation. It is the fear of not sleeping that raises the heart rate and tenses the muscles; fear, not anxiety. Here is where insomnia becomes intractable, because it deploys fear to act like anxiety. Where fear is a response to an external threat, insomnia is almost unique in giving rise to a fear that then causes the external threat. Being afraid of the saber-tooth tiger is what makes the tiger keep coming back – not seem to come back, but in fact come back. It is no use to say ‘don’t be afraid’. There is a tiger in your bedroom, you ought to be afraid. But it’s not a tiger you can ever overcome by freezing, fighting or running from, so all your mechanisms for dealing with a real threat fail, giving rise to more fear, which keeps the tiger coming back. A vicious circle of Euclidean perfection.

Sleep. Sleep. Like money, you only think about it when you have too little. Then you think about it all the time, and the less you have the more you think about it. It becomes the prism through which you see the world and nothing can exist except in relation to it.
