Just like human, most animals need sleep to function daily and live a healthy life. However, not all animals have the same sleeping pattern as humans- with some relying on little sleep, and others spending over half of their day sleeping.
Scientists are still unsure of a lot of facts when it comes to animals and sleep. Huge studies are still on-going on whether animals experience dreams just like humans. Although many studies prove that animals such as dogs may dream due to their movement during sleep, scientists are still not 100% certain.
