Creatures as wide ranging as octopuses, insects, mammals and more show signs of sleep phases. For some parts of sleep the brain is less active, during others REM, RAM or other body movements and changes indicate a more active brain. This suggests that either dreaming evolved multiple times in parallel... or it is something a very very basic common ancestor of all animals life experienced.It also suggests that something about brains means sleep is needed. (IMO)

My armchair guess is that if a creature uses it's neurons to have memories then they MUST dream. Maybe if you can't dream you can't make memories?

@futurebird something I remain curious about is whether, if and when we develop an *actual* synthetic intelligence, it will turn out to need sleep.

@futurebird Isn't one of the theories, that dreaming is our way of processing the experiences we've had? Which obviously requires us to be able to remember them.

@futurebird "You can think of [the brain as] like having a house party. You can either entertain the guests or clean up the house, but you can't really do both at the same time."That's a quote from Prof Maiken Nedergaard at the University of Rochester Medical Centre in New York, whose team believe that sleep is about flushing away "waste", the chemical byproducts of cognition.I like this theory because it means when you're feeling groggy from lack sleep, it's because your brain is dirty!

@futurebird i wonder if dreaming doesn't actually do anything and is just a side effect of whatever it is your brain does while sleepingthings just sort of misfiring while your brain is cleaning up

@futurebird I have read that dolphins sleep with half their brains at a time, so the other half stays awake.

@futurebird do armchairs dream of plush sheep?

@futurebird I would put down a £5 bet it's evolved in parallel. However it's probably common enough that it's necessary for the way that brains work.Much the same as blood and eyes evolved several times more or less independently 🙂

@futurebird some scientists argue that jellyfish sleep too!

@temptoetiam If they sleep then I think we need to check on the plants too. Damn.

@alienghic Ravi Nath, the paper's co-first author and a graduate student in the Sternberg laboratory. "But jellyfish are the most evolutionarily ancient animals known to sleep. This finding opens up many more questions: Is sleep the property of neurons? And perhaps a more far-fetched question: Do plants sleep?"This makes me feel less silly about wondering about plants. Plants don't have neurons. So, my guess is that they probably do not "dream" ... but rest and active phases may exist?

@futurebird @alienghic @miguelpergamon Olaf Stapledon posted a species of intelligent civilized plant people. They moved around and did stuff at night.Photosynthesis put them into a total bliss sleep
