Did you know octopuses change colors in their sleep? At least scientists believe that is because they are dreaming . In the documentary Octopus: Making Contact by PBS, the marine biologist David Scheel of Alaska Pacific University, presents an incredible footage of a sleeping octopus changing color while dreaming .
The dreaming octopus from the footage, changes color while she is sleeping. Since we know that octopuses uses their amazing color-changing ability for camouflage based on what they are seeing, it has been suggested that the octopus Hiedi changed her colors while resting based on real-life encounters.
Also it has been suggested that could be a similar reaction as REM ( Rapid Eye Movement sleep) which is a unique phase of seep mainly found in mammals and birds, distinguishable by random/rapid movement of the eyes.
As expected the footage had became viral on Twitter and other social media platforms.
