I'm facing a similar issue and this seems like an interesting approach to resolving it. However I don't really see visualizations when I close my eyes and I haven't noticed them when falling asleep. Is this just something that takes more practice to notice, or only some people see them? If this only works for some people is there another similar approach to hook into the falling asleep process?
That quote from Claude to its own rules was pretty interesting, I wonder what the prompt was? I wrote a response to it here: https://www.zappable.com/p/the-soul-of-claude
