Replying to the edit! That is super interesting. Is that why sleep walkers get violent when someone attempts to wake them up? I don’t know if it is a myth, but I have always seen in a bunch of places that you are not supposed to wake someone up who is sleep walking. In this instance too, someone acting out their dreams while still in bed.

Side note, I have always heard stories of elderly people or people near death talking and or moving in their sleep a lot. This seems interestingly related. I guess since a small factor of Alzheimer’s and Parkinson’s exists in my family tree, I know an early symptom I should look out for.

So actively waking my self up cus I was dreaming and I noticed I could just hear and see while my body was paralyzed does count ? I was yelling at my sis to wake me up cus somehow I was dreaming she was visiting.

I woke up a first time in my sleep, sis gone. Then I noticed I was still paralyzed,I was thinking to myself wake the up! Numerous times.

And then I woke up. I hate quick naps.

What if you do but only once in a blue moon? I punched my partner in the back in the middle of the night once while Dream Me was fighting a giant bee, but I don't generally do things like that.

I'm not an expert on the etiology nor the mitigation, nor really any part of these diseases. I simply heard that statistic recently, did some research to validate what I had heard, and then posted because I found it so wild that these sleep behavioral symptoms were indicative of future pathologies.

  1. This was a very small sample size.
  2. I’m curious what the data also says about the percentage of people with the studied brain maladies also physically acting out their dreams prior to showing other symptoms.

Let’s say 10% of the population will eventually get one of these conditions, but only 1% of the population physically acts out dreams, then that explains only 10% of the attributes that correlate to these conditions.
