Scientists observed sleeping octopuses and saw their brains enter a deep sleep like ours.
This deep sleep is similar to a dream state in mammals, so octopuses may also dream.
For the study, scientists spied on multiple sleeping octopuses.
By studying the octopus's brain activity, the team found that these cephalopods have similar active and quiet sleep cycles to us mammals and that certain periods of their active stage resembles rapid eye movement sleep.
REM sleep is often when humans dream, leading scientists to wonder if octopuses may dream like us.
