Do Animals Dream?

Yes of course they do, you can see cats or dogs with their whiskers twitching and their legs making tiny movements and they make quiet noises as they are obviously dreaming of the chase.
You can even make a cat dream, just stroke the tips of it's whiskes gently while it's asleep and about a minute later it will start to react (well our brains are rather furry so it takes a while).

I tried to make my cat dream once... stroked his whiskers gently while he slept.

Retribution was swift and sure. It is a lesson that will not grow dim: Don't stroke my whiskers while I am sleeping, dummy!

Are you kidding? Of course they we all do !

Yes, How about Monkeys dreams of making Human?

Domestic animals probably sleep as much as they want, therefore dream as much as they want. I know the animals are laughing at us. Or at least, when they get more sleep than we do...

Hmm... Doorman raised an extremely interesting point. Sponges are animals; and I'm going to go out on a limb and state that I believe sponges don't dream. But as you move up and down the intellectual chain from both ends... at what point of "animal life" does the ability to dream begin? Is it only mammals? If so, does the most rudimentary mammal dream? What physiological trait of a brain is necessary to produce dreams? Is it pure intelligence that is the deciding factor? Does a lobster dream? What is the most intelligent of the insects? I'm guessing that birds do dream. Lizards? Fish? Is it the backbone that is the deciding factor? Perhaps that is it. All vertebrates dream. I imagine there has been a study somewhere. But I'm going to go with vertebrates.

My girlfriend dreams of being a dog, chasing cats. All night growling and barking. JE
