It sounds like this study has a series of problems. No control group, no reference measurement, no predefined hypothesis, and it doesn’t seem to mention number of participants, unless I missed it suggesting that it’s a small number.
From this read I doubt it would replicate under stricter experimental conditions and with more rigor.
Edit: Oh and I forgot that the noted effect being equated with creativity is somewhat unreliable. Essentially they where given a math problem that randomly seems to also give an answer you can find in the number itself, but anyone would know that this can’t be relied upon and might lead to errors if you just assume that’s the answer. That is unless your unfocused or just less logical. They could repeat the test and replace the sleep element with getting drunk and they would likely see an effect.
