What is ACTUALLY happening when you ‘fall asleep’?
In: 34
Being awake or conscious is like drummers standing in a circle all beating their drum to the same rhythm. All the drummers drum in unison and if one changes the rhythm the others follow suit. They are all aware of each others rhythm, so act in unison and are aware of each other. This is essentially how the different parts of the brain communicate and remain conscious and aware of the world around us.
Now imagine one of these drummers gets tired and starts beating slower, then another gets tired, beats a bit slower than the first then another and another. Suddenly none of the drummers are in unison and lose the overall rhythm they had earlier. Each one just does its own rhythm and thus is no longer aware of the other drummers or the outside world, This is you falling to sleep until the drummers decide to beat in rhythm again, around 7-8 hours later when the sun comes up.
