I can't say the same, but conversely if I have poor quality sleep characterized by too much dreaming, the next day I'll wake up with a feeling that's best described as a light burning sensation in my head. It's not painful, just unpleasant.

I've often theorized it's due to the glymphatic system being unable to perform its job properly the previous night. I've noticed anything that impairs sleep will do this: from failing to take my usual magnesium supplement before bed, to alcohol, to the incorrect ratio and dose of cannabinoids.

Poor quality sleep: burning head sensation plus usual tiredness.

Good quality sleep: wake up feeling great. Sadly no "clean" sensation, however. That does sound interesting. :)

It's worth noting duration doesn't matter. I can have 4 hours of quality sleep and just be tired sans any burning sensation, or 8 hours of poor quality sleep and wake up with it. Definitely weird.
