Today I got some good news: my counter-signed contract with O’Reilly came back. It’s now official—I’m writing an ebook on Quantified Self self-experimenting with sleep.
I look forward to include LW-related material on the perils of self-experimenting and bias. Suggestions from readers on what they’d like to see or material covered?
Congrats! Some topics I’d like to see, most of which you’ll probably already cover (though they may be more on general “sleep” than “self-experimentation and sleep”):
1) distributions of sleep in general population and any information you can find on correlates
2) any well-powered interventions to see whether sleeping more correlates with success in any way (more working memory, decreased bias, real-world measures, etc.)
3) whether lucid dreaming really might make your memory worse because you need that REM sleep to be “random” (generally, trade-offs to lucid dreaming)
4) trade-offs in sleep: what are the upsides/downsides to more, what are the upsides/downsides to less, and how might drugs like modafinil play into this.
I don’t know of any studies to support this, nor have I done sufficient systematic investigation of the phenomenon, but I am a lucid dreamer, and I have noted a general trend of increased alertness and improved memory of dreams after lucid dreams. I’m not well-versed enough in the science of dreaming to propose any credible explanation for this, nor do I have evidence that memory in general is improved. However, it has been consistently true that I have better memories of lucid dreams than non-lucid ones, and I am more likely to wake up fully alert after a lucid dream than is normal for me.
I know anecdotal evidence may not carry a great deal of weight, but I hope this is helpful.
Those are some pretty challenging questions. #1 just requires some research into sleep tables and aggregate data, which while tedious is not necessarily difficult. #2 is worth looking into as a way to justify interest in sleep specifically.
But #3 seems impossible to answer now, since there are few enough lucid dreaming studies that likely none of them have investigated it, and I would expect any effect size to be small (which means the existing studies which use no _n_s <~30, for the obvious reason of it being hard to find lucid dreamers, will be badly underpowered to discover it) since lucid dreaming is fundamentally rare and dreams short in duration. It’d be like asking whether getting 30 minutes less sleep is bad for your memory: possibly, but you’re going to need an awful lot of data to spot the ill effects!
Question #4 is somewhat similar but may be answerable for specific values.
That’s what you get for setting pretty high standards with your previous work.

Since the book is on self-experimentation, couldn’t you see whether you yourself have done worse on DNB/SR flashcards on days after you have some degree of lucid dreaming?

I haven’t worked on lucid dreaming in years, because I was so unsuccessful; I never got beyond improving my dream recall with a dream journal.

Edit 7/30: fixed typo in #4

Scientifically backed evidence on waking up and falling asleep?
