Why sleep is a powerful tool for a writer

If you have writer’s block, stop trying to think harder–go to sleep, and you’ll unlock the solution for your writing.

If you’re stuck on your novel—can’t figure out the next scene, the right turn in the plot, or how to solve a problem you’ve been staring at all day—there’s a solution most writers resist.

Stop thinking about it. Go to sleep.

That might sound flippant, but some of the most creative minds in history deliberately used sleep as a problem‑solving tool.

When we concentrate too hard, we actually shut down parts of the brain responsible for insight and creative leaps. Sleep—and especially the moments just before it—lets those systems come back online.

Dalí, Edison, and the Power of Letting Go

Salvador Dalí knew this well. When he felt blocked, he would sit in a chair holding small metal balls in his hands. As he drifted towards sleep, his muscles relaxed, the objects fell, and the clatter woke him.

In that brief moment—just as conscious control dropped away—ideas surfaced.

Thomas Edison used a similar technique, holding a watch while dozing in a chair. The sound of them hitting the floor would wake him, often with a fresh solution already forming.

What they were tapping into is now known as the hypnagogic state: the borderland between waking and sleep, where the brain becomes more associative, less rigid, and more creative.

It’s the opposite of forcing an answer.

Writers Do This Too (Whether They Realise It or Not)

Graham Greene understood this intuitively. At the end of each day’s work, he would read over the pages he’d written before going to bed. While he slept, his mind continued to process the material, and he often woke knowing exactly what he needed to write next.

This is a powerful lesson for crime writers in particular.

Plotting a mystery, solving a narrative puzzle, or finding the right psychological motivation isn’t always something you can brute‑force. Often, the solution arrives only after you step away.

How to use sleep in your crime writing

You don’t need to hold keys or watches (though you can, if you like). The principle is simple:

• When you’re stuck, stop forcing progress
• Read over the section you’re struggling with
• Then disengage—sleep, nap, or walk away
• Let your subconscious do the work

Very often, you’ll return with clarity you simply couldn’t reach by staring harder at the page.

Sleep isn’t lost writing time. It’s part of the process.
