For decades, dreaming has been hypothesized to contribute to emotional memory processing. Here, we investigated how reactivating highly emotional autobiographical memories prior to sleep affects dream content and subsequent emotional appraisal of these memories. #sleeppeeps #psychscisky 🧠🟦

Admirable clarity @science.org
The Trump administration hates academic science funding, full stop. They hate where that money goes, and they hate who it goes to. They want to keep all that money for themselves, to hand out to favored cronies who can help them get elected and to steer yet more money and more power back into their hands.

That’s it. That’s the story
