A breathtaking video showing an octopus change color while dreaming has left the internet in awe.

You can see the eight-legged creature changing from light to dark colors while hanging upside down.

Marine biologist David Scheel explained: “If she is dreaming, this is a dramatic moment. You could almost narrate the body changes and narrate the dream.”

“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.”

“This is a camouflage like she’s just subdued a crab and she’s just going to sit there and eat it, and she doesn’t want anyone to notice her.”

“It’s a very unusual behavior to see the color come and go on her mantle like that, just to be able to see all the different color patterns flashing one after the other, you don’t normally see that when an animal’s sleeping. This really is fascinating.”
