Night terrors occur during the deepest part of sleep, non-REM sleep, and are a reaction of being 'startled awake' when the fear center of the brain is suddenly and inexplicably activated.

In fact, it is not quite correct to say 'scared to wake up', because although the action is very like being scared to wake up, in fact, people are still asleep, and they will not remember that they have experienced this period after waking up. In contrast, the more unlucky person is sleeping next to the pillow! The rate of night terrors in children is much higher than that of adults, and if there are night terrors in adults, pay attention to whether you have eating and sleeping disorders, and pay attention to whether this may be a precursor of narcolepsy.
