The Stages Of Sleep

When we sleep we go thru five stages of sleep stage 1, stage 2, stage 3, stage 4, and REM (rapid eye movement). These five stages cycle from stage 1 to stage REM, then it just starts all over again.          

                          

Stage One: Light sleep we can be awakened easily, everything in our bodies is moving slowly 

Stage Two: Our eye movement completely stops, our brain waves don't completely stop they just become slow and occasionally we get rapid waves

Stage Three/Four: Is very difficult to wake someone up, we get really slow brain waves, stage four the brain produces exclusively brain waves, in these stages, we have no eye movement, no muscle activity 

REM: Our eyes move in various directions, our breathing become more rapid, our heart rate increases, some of our muscle become temporality paralyzed 


In my psychology, we were learning about our brains and about our sleep. We would get into really good interesting discussions, we would share some of the experiences we have had in our sleep. Some of my classmates had some experiences that I could also relate to. I'm pretty sure this has happened to everyone when you're sleeping and all of a sudden you feel like your falling down from a really high place or simply falling down from your bed when in reality your not. That happens when your brain thinks you're dying so to make sure you're okay it gives you that crazy feeling. I was surprised when my teacher explained this to me. Also, you might think you don't dream every night but, you do you just don't remember. When your sleeping so many crazy things are happening and you don't even know.
