  1. The phenomenon of hyper-vigilance or cognitive hyper-arousal, you mark the event as significant for you and the psyche allocates resources so as to prepare for it. This is a normal adaptive process

  2. We just don't want to hear that nasty sound. A person has set the alarm for 6: 00 , and the body already subconsciously knows that it is better to wake up before that in order to avoid negative emotions.

  3. This is due to the internal clock(biological).If you have an important meeting, most of the time you think about it a lot and set yourself up to “not oversleep”.I do not know the essence of the process(I am just making observations about myself):most likely, the brain adjusts the cycle and awakening.This tool, with proper skill, can and should be used.

    And it works just fine-just clearly scroll in your head what you need to do and at what time,and preferably imagine how you will do it.Whether it's waking up or remembering to buy something, or calling someone, 99% of the time you will succeed, and you will remember or wake up.

  4. You wake up not only 5 minutes before the alarm, but also many times during the night, just do not remember these awakenings. If an important meeting, a night flight, etc. is stressful, then there are more such awakenings, and the period between them is less. But this applies to cases when you need to get up earlier than you are used to. In all other cases, awakening is regulated by the circadian rhythm (biological clock)

  5. Well, this applies not only to the meeting, but in general. If a person needs to wake up, for example, for a train at 3 am, then he will also wake up in most cases before the alarm clock. I won't give you an exact scientific answer (I don't want to go to Google and copy from there), but the bottom line is that our brain has its own clock, its own alarm clock, and when necessary, it works :)�

    Just eat and that's it.�

    Well, since you're already minus it, then :

    German scientists have discovered hormones that send a signal to the brain, the action of which can be compared with the mechanism of an alarm clock.

    The hormones adrenocorticotropin and cortisol send a wake-up message to the brain. This explains why some people can wake up on time without an alarm clock. Both hormones are produced by the body in anticipation of stressful, unusual situations. For example, school exams, conflict situations, a presentation, etc.

    In the same study of German scientists, it was also recorded that the level of hormones increases in the later stages of sleep, provoking the expectation of the moment of awakening. Scientists generally agree that sleep is a state of unconsciousness, but the same study showed that the brain is in a state of alert consciousness. The researchers believe that based on the obtained scientific data, it is possible to develop a course of therapy for those who have difficulty getting up early, work in different shifts, or, due to work necessity, are forced to sleep at different times of the day.
