Piper Dog was snoozing and suddenly his paws, tail and muzzle started twitching.
I’ve always thought that’s a sign of a dog having a dream.
But then I I realized that I’ve never seen any of the Piper cats do that.
How come? Do they not dream? Are they such aristrocats that even asleep they don’t do something as vulgar as those common dogs, who just don’t keep their emotions under control?
One of my cats sleeps on my lap and she definitely twitches and runs in her sleep. The other one crawls up on top of me and sleeps there, and she dreams out loud, too. I guess the question is why are the Piper cats holding out on you?
Every cat I’ve had has done this, too. Typically, it’s the feet and the tail twitching. Sometimes, they’ll curl their lips, twitch their whiskers, or make little mewing noises, too.
When my cats dream, they go limp, twitch, and chatter. Usually their jaw will hang open and their eyes might be partially open, but the third eyelid is fully closed.
Okay, the obvious follow-on question: Do humans twitch, move their paws, or mew or growl when they dream? We know humans dream.
We’ve been told that humans have some mechanisms that disconnect the motor nerves from the brain while we sleep, so we don’t act out our dreams. We’ve been told that this can happen while we’re still partly awake, being the cause of “sleep paralysis” episodes that happen to some people. We also note that some people talk in their sleep or even sleepwalk (which may entail activity even more elaborate than just walking).
Why is this not more common in people? Why don’t dogs and cats get up and sleepwalk?
Are we all talking about basically the same phenomenon here?
Humans do twitch during hypnagogic jerks or rapid-eye-movement sleep.
If you are talking in your sleep, jumping out of bed, flailing, and so on that is considered a sleep disorder. (Maybe not sleep talking.) There is actually a whole list of scary parasomnias like sleep walking, sleep eating, sleep sex, sleep paralysis, exploding head syndrome, …, and of course REM sleep behavior disorder, which is associated with a lack of normal sleep paralysis which should keep you from thrashing around and acting out your dreams.
Oh, I can almost always tell when my Maggie is dreaming. She “talks” in her sleep, and sometimes she’ll just jerk awake and look around all startled like, “what happened?” Like she was having a nightmare. Poor kitty. LOL
There could be some truth to dogs making more overt movements while dreaming. Dogs are pursuit hunters, while cats are ambush hunters. Dogs dream of running after a rabbit, while cats dream of sitting perfectly still before pouncing on that mouse.
