I had absolutely debilitating insomnia for my entire life. In the last couple of years I discovered something interesting. I’ve got a condition called aphantasia which means that I cannot see any images in my mind. For my whole life I heard the phrase counting sheep and thought it was a metaphor. Just like. Thinking about sheep since visualizing wasn’t something that I thought people could do.

Anyway, in researching about the condition I found an article online for an exercise where you can work on trying to visualize something. Basically you close your eyes and use the flashing remnants of vision to try to force a shape to exist. Sometimes you need to push on your closed eyes and a little pressure will cause some patterns to appear. You’re supposed to do this exercise while talking to someone outloud. Even if it’s just making a recording. The article I read said you must say it out loud or you will fall asleep. Me having never fallen asleep in my life without hours of concerted effort completely ignored this warning and much to my surprise it absolutely made me fall asleep within minutes.

Ever since then I’ve been able to use this technique to fall asleep every night. It’s like my mind finally learned how to do it. Most of the time I don’t even need to do these exercises any more.

That being said I was so pleased with this side effect I never even tried the say it out loud to try to improve mental images and I still can’t see anything in my minds eye. But being able to sleep every night without fail is a freaking miracle. So I highly recommend giving it a shot.

Here is the original instructions I found on it. https://photographyinsider.info/image-streaming-for-photographers/
