An octopus changes color while sleeping / dreaming
Information
Video published by Nature on PBS
This video shows us, in high quality, an octopus while it sleeps.
The narrator explains that it is probably having a deep dream in which it catches a crab on the ocean floor. Each color change is usually used to surprise / attack prey, then when it rises above the bottom, it generally turns black, and finally switches to camouflage mode to enjoy its crab in a quiet corner.
For those who still doubt that animals can dream, this video might change your mind.
