Alcohol is one of the most powerful suppressors… and honestly, that’s putting it mildly. It’s not just a bad night’s sleep; it’s a neurological shutdown of your dream factory. If you’ve ever woken up after a few drinks feeling completely unrested, this is the biological reason why.

Meaning
The core message here is brutally simple: alcohol doesn’t just help you fall asleep, it actively sabotages the most restorative, dream-rich phase of it.
Explanation
Look, we used to think a nightcap was a good thing. Right? It sedates you. But what’s happening under the hood is a different story. Your brain isn’t sleeping naturally; it’s been anesthetized. And the first thing to go is REM sleep. That’s the stage for memory consolidation, emotional processing, and creativity. Alcohol bulldozes it. It’s like your brain is trying to run its most important software update, and someone just yanked the power cord. The real kicker is the rebound effect later in the night, but the initial, deep suppression is what Walker is really zeroing in on.
