Mini summaries part 3 (Glitches)

Hello. Welcome to Mini summaries part 3. If u don't get what am I talking about, pls Check the previous posts.

Sleep finally gets to me. One second I close my eyes and the next I open it after 8 hours of sleep. But How the hell I never felt those long hours of sleep. It definitely felt like minutes, even seconds. What really happened while I was asleep??

In your body, maybe not much, but in your brain. I am sure a lot has happened.

Let's start with the easy ones.

When you sleep you get into 4 stages of sleep.

The first stage is called. REM (rapid-eye-movement) stage. This stage is the most active stage ( the brain here is very active actually ) and also this when all dreams happen.
The second stage is called NREM (non-rapid-eye movement) stage. This stage has 3 substages which only differs (as far as we know offcourse) in the type of signals shown in this stage.
In NREM less brain activity and no dreams.

What really controls your dreams and sleep dysfunctions is REM.

Then if you don't know how the hell you spent from 6 -9 hours a day like a dead person. u better know that the reason is The REM stage, where your brain nearly functions as like you are awake except your motor neurons.

So your brain is quite active, your internal organs are active.
SO IN REM, YOU ARE VERY MUCH AWAKE EXCEPT YOU ARE NOT MOVING AND CLOSING YOUR EYES
AND OFFCOURSE UNCONSCIOUS.[x]

" I opened my eyes after a long sleep, starting to fully wake up and sit on the bed, but I couldn't. I couldn't move my hands or legs. I felt like I was chained in my own body. As if someone was standing on my chest. I tried to untie my self from this strange hold. But in vain. I looked at my bedroom door, and there was a man. He was so tall and dark. He was so creepy. He started to walk towards me. I screamed from the top of my lungs. But nothing came out "

This is called sleep paralysis. There are many theories behind this phenomenon. But the scientific one is a glitch. Yeah, you heard me right. A little glitch by the brain.
Your brain is perfect just the way it is. But sometimes when you wake up. It doesn't switch back the motor neurons( which controls your movement) right away, so you feel like you are trapped and the huge dark man you saw. He is just a hallucination caused by your brain due to your fear and uncontrolled emotions.

On the other side, there's sleep walking, which is one of the most common dysfunctions.
The same glitch in the brain but in reverse. The motor neurons are this case isn't switched off. No its on. As in awakeness. so you walk, talk, or move or jump in your sleep... Which is called sleepwalking.

And last but definitely not least the infamous hypnic jerk.
I am sure you felt it a time or two. Maybe more. But when you start sleeping and then feel like you are falling and then your leg is jerked. This is when your brain mistakes your sleep with dying. so, it tries to switch the motor neurons back on quickly and wakes you up.

Glitches or not, your brain is amazing. It is the greatest creation of all times. Just try to be healthy and know it better, cause your true power lies in it.
That's it, see you in part 4.

This is a free writing style based on my understanding of the amazing book by Dean Burnette..the idiot brain.
