The effect of deprivation of rapid eye movement (REM) sleep upon retention of a passive avoidance response in rats was studied. An incompletely-learned avoidance response was established in one trial by shocking the animals when they stepped down from an elevated platform. Fourteen animals were then deprived of REM sleep by placing them on small inverted pots in a pool of water. Twelve control animals were placed on slightly larger pots which permitted normal sleep. None of the REM-Deprived animals showed retention of the response when tested the day after training, whereas sixty per cent of the control animals showed retention. The results suggested that REM sleep is essential for adequate adaptation to new experiences, especially those which cannot be completely comprehended upon first exposure.

Dreaming is the subconscious minds way of dealing with all the information it gets during the day. There is a lot of sensory stimulus during the day, too much for our minds to directly address and so we ignore many of the little details. When we sleep all that information is blended together in our subconscious to form dreams. Or at least that's what I think happens...

My dog lays there making funny noises and small barks wiggling her paws arround and blinks her eyes alot (with them shut) while shes asleep. and to my knowledge dreams would either require a cauntious memmory of events and places to put together into a dream, or if you believe in the esoteric they would be and need a traveling mind/spirit/contiousness threw the astral plane and both require a cauntious being.

We're not the only intelligent species but we are the only species with such complex language.
Other animals might have a sort of consciousness but it wouldn't be as advanced as ours.

We still underestimate our fellow earth creatures, and overestimate our own intelligence. If one day we could learn even just one of their languages, we would probably be so surprised at their intelligence.

I know animals have communication but it is not the same as human language,
For instance, I have no doubt a pod of dolphins can alert each other to the presence of a shark or where a tasty school of fish is swimming but I do have doubts that a Dolphin could dictate a novel length work of fiction.
So...how do we know all animals dream? What, flies dream too? Ants? Everything? That's incorrect IMO...what tests have been done to show these small animals are dreaming? "Brain activity" isn't necessarily dreaming...however, I know dogs and cats can dream because I've had several that make noises and move their legs as if they were running in a dream, and things like that. Dreams are an extremely complex thing, our brains are able to generate entirely new worlds and personalities which we interact with, without even being aware it's all just an illusion most of the time. The ability to dream indicates an advanced form of intelligence IMO...it indicates a type of self awareness, it shows they have conscious perspective as an observer. Not all animals on Earth do dream, but I assume many probably do...only when you realize many animals are more than just a simple organic machine, but are in fact self-aware individuals with clear personality traits, can you form a deeper connection with them.
Why have all mammals evolved to do it? Birds do it too. Despite it being a very risky activity to the animals surivival as it is left vunerable while sleeping, none at all have evolved to not dream. Its almost as if dreaming is essential to life.
