A sleep tool to try
The cognitive shuffle (serial diverse imagining, from cognitive scientist Luc Beaudoin) works by occupying your mind with random, unconnected images so it can’t keep running worries or plans.
1. Pick a neutral word with no emotional charge, like "blanket" or "garden."
2. Take the first letter (B). Think of a word that starts with it, like "banana," and picture it vividly for 10-15 seconds.
3. Move to a new, unrelated word with the same letter, like "bicycle," then "bridge." Don't link them into a story.
4. When you run out, go to the next letter and repeat.
5. If you lose track, don't fuss. Pick any new random word and keep going.
The point is randomness: no logic or narrative, just a series of disconnected pictures. That mimics the loosening thoughts you get as you fall asleep.
