They dream in gifs

Research published in 2021 tracked octopuses’ sleep schedules. The scientists found that the animals had sleep states similar to REM states in humans, when we dream.
If the animals are dreaming, though, the researchers don’t think they have dreams as complex or lengthy as our own. “It should be more like small video clips, or even gifs,” one researcher told Gizmodo. As new approaches to studying octopus minds come to bear, we may get a better understanding of how they think.
