How does the sleeping brain retain the intentions of a person’s conscious self (like not moving all or part of the body, or waking at a very specific time) and then actually carry them out?
In: Biology
Can’t answer the first part properly, I’m really not specialised in sleep.
For the second part, it’s because we have an internal clock that is synchronized on the natural sunlight, with the help of this clock your body knows more or less what “time” it is and that’s why you can wake up regularely at a given time without the need of an alarm clock.
It doesn’t work every time because depending on your level of stress, fatigue it can disturb it. Alternating between night/day shift at work disturb it as well.
