A mesmerizing video of a sleeping octopus shows the creature changing colors in a manner which suggests that it may be dreaming. The remarkable footage was released by PBS as a preview for a forthcoming documentary showcasing the work of marine biologist David Scheel as he studies an octopus dubbed 'Heidi' that he keeps in his home. In the clip, he marvels that "last night, I witnessed something that I'd never seen recorded before."
In the moment that left the marine biologist amazed, the body of the sleeping octopus inexplicably begins displaying different colors and patterns. Based on the nature of these changes, Scheel not only theorized that the creature was dreaming, but that it was possible to surmise what sort of scene might have been unfolding in her mind. To that end, he first imagined that "she sees a crab and her color starts to change a little bit, then she turns all dark, octopuses will do that when they leave the bottom."
