All I know is my dog sometimes yips in his sleep, and it can be fairly loud-- I will forever wonder what he's yipping at, or how that behavior could possibly be selected for. Brains are weird.

I noticed mine seems to have vivid dreams with barking after being woken up at night. Interestingly, the paper claims: > It is notable that approximately 50% to 70% of the time subjects report having a dream upon a sudden waking during sleep.

  That's interesting. I keep a dream journal and most of my entries are on days where I had interrupted sleep.

  Waking up and realizing you were dreaming is not the same as waking up and then dreaming

Dogs and their ancestor's wolves are pack animals, maybe the sleep barking wakes the other pack mates making them more aware of their surroundings and better able to defend the pack from threats during the night? Maybe even The barking itself helps to ward off threats that would otherwise attack a sleeping animal. Is there even anything that preys enough on wolves where enough of them are being killed by it that the sleep barking would be selected against?

I thought dreams only happen durring rem and you are paralyzed durring rem stages. So you wouldn't be physically reacting to anything. I think those movements only happen in other stages of sleep

  What's your source for the paralysis being complete during REM and movements happening only during other stages? That seems suspicious to me given that a) REM is named for movement, and b) these mechanisms definitely aren't perfect, as things like night terrors and sleepwalking demonstrate. For what it's worth, the American Kennel Club claims that dog motions do happen during REM: "We can’t know exactly what dogs dream about, but researchers have observed that certain breeds of dogs tend to perform breed-specific behavior in their sleep when the pons is inactivated. Pointers, for instance, point, and English Springer Spaniels exhibit flushing behavior during REM sleep." https://www.akc.org/expert-advice/lifestyle/why-dog-twitch-in-sleep/ https://www.akc.org/expert-advice/lifestyle/why-dog-twitch-i...

    This is fairly easy to google its pretty basic sleep info... https://www.sciencedaily.com/releases/2012/07/120711131030.htm https://www.sciencedaily.com/releases/2012/07/120711131030.h... sleepwalking isn't related to rem stage, most movement doesn't occur during rem stages https://www.mayoclinic.org/diseases-conditions/sleepwalking/symptoms-causes/syc-20353506#:~:text=Sleepwalking%20is%20a%20disorder%20of,eye%20movement%20(NREM)%20sleep https://www.mayoclinic.org/diseases-conditions/sleepwalking/.... https://www.uofmhealth.org/health-library/hw48331 https://www.uofmhealth.org/health-library/hw48331 I don't think its farfetched to guess this applies to other mammals

      I'm not saying it isn't the general case. I'm saying it isn't absolute. I also am not saying sleepwalking is part of REM; I'm saying it is an example of how mechanisms for quiescence are not perfect. And since we're talking specifically about your claim about dogs, I'd like the dog reference specifically, please.

        https://www.petmd.com/dog/general-health/do-dogs-dream https://www.petmd.com/dog/general-health/do-dogs-dream This suggests that all mammals brain work simmiliar and are paralyzed durring rem. I'm not sure why your bringing up sleepwalking and night terrors, those don't occur durring rem, so it had nothing to do with paralysis disfunctioning And I'm not even sure what point your getting at with your comments? Just demanding sources. I feel like you can Google these things your self
