Incredible footage captures a sleeping octopus changing colour while dreaming

PBS

An octopus has been filmed changing colour whilst sleeping, and scientists think it might be due to it dreaming.

So our eight-legged sea creature friends can dream, who knew?

The footage, captured by PBS for an upcoming documentary Octopus: Making Contact, shows the mysterious creature asleep and changing from grey, to yellow, then almost invisible as it camouflages itself against the ocean.

Scientist Dr David Scheel imagines what the octopus might be dreaming about. Narrating calmly, he says:

"She sees a crab and her colour 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 now she’s going to sit there and eat it and she doesn’t want anyone to notice her. …This really is fascinating. But yeah, if she’s dreaming that’s the dream."
