Why does nobody remember the moment they fell asleep?

Do you remember how you lay down in bed, remember what you were thinking about, but the moment of transition to sleep seems to disappear.

The thing is, during the process of falling asleep, the brain gradually decreases the activity of the systems responsible for attention and the formation of new memories.

Therefore, this transition is usually just not saved in memory. But it gets even more interesting.

Sometimes it feels like you couldn't fall asleep for a very long time, even though you were already sleeping.

Scientists have found that in the lightest stage of sleep, a person can be sure that they are still awake.

If awakened at that moment, they often say: "I wasn't sleeping at all."

Such strange things our brain sometimes does. What are your thoughts on this?
