When my sister and I were younger and had to share a bed, she would often complain that I spread out too much and made a complete rotation during the night like a clock. I would always say “NO I DON’T!” because I woke up in the position I started in. But I later realized she was right because when I was about 10 my friends and I started talking about dreams, so I was trying to remember them. I remember waking up after one dream and lying almost horizontally on the bed and my sister on the edge, trying to get some sleep. Another night I woke up from some nightmare and found my head where my feet started and vice versa.
Now that I’m a teenager I have my own (twin-sized) bed. I don’t change positions like that any more- if I did I would fall off .
But why did I move so much when I was younger? Is it because I subconsciously know I’ll fall off of my small bed? Maybe when I was younger I was just being a pest and wanted to get on my sister’s nerves? Is it something you grow out of? And doesn’t sleep paralysis prevent you from moving each night?
well, SP only stops your body from moving during REM sleep, and even then it’s not complete. one of the ways that Stephen LaBerge proved lucid dreaming to be real, was that he tested lucid dreamers in certain ways.
he brought a few lucid dreamers in, and had them move in sertain ways during their LD’s. when you move in your dreams, it directly effects twitches in your muscles. if you move your arm in a dream, your RL arm twitches slightly.
when you moved though, it was in deep sleep, when your body is most active regenerating, and your mind is farthest asleep. this is also when sleep walking accures.
hope I answered your question
I think sometimes your SP is more full, and sometimes it’s not as full.
One of my last LD-s ended this way: i was taking off my boots in LD, and needed to move my leg. So i lifted my leg, but at the same time it corresponded by moving my physical leg in my bed what made me wake up
Actually that’s in nREM sleep, sometimes also referred to as deep sleep but dont confuse it with deep dreamless sleep (if I remember correctly thats dream phase 4), during which you can’t move a lot.
Another thing to it is connected with blood pressure and muscles functions.Again im sorry i dont remember much more but i was a lousy student- i just read it somwhere back then that changing positions while sleeping is somehow physiologicall need and only words that knock to my head are “blood pressure” and “muscles”.
