Early morning awakening

There are signs of early morning awakening in the past week. 

I wake up in the middle of the night, specifically around three o'clock.

In most cases, I fall asleep without realizing after a short time.

I have not a pathological impression.

But, one thing I can say for sure is that I'm a little nervous about the new school year.

Although I am really looking forward to that, I must be careful.
