What happened

Some mornings when you wake up, your head is fuzzy, your body is heavy, and you don’t feel rested.

Why it matters

But did all that dreaming actually wear you out?

Common ground

We all dream, but not everyone remembers it Most dreaming occurs during rapid eye movement (REM) sleep, which makes up 20–25% of our total sleep time.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
