A monster you can't sleep with

You came back from work tired and wanted to sleep... But you knew that Rain was somewhere nearby, so you had to endure and drink a lot of coffee out of habit. You learned your lesson long ago. If you fall asleep at night or during the day, Rain immediately tries to attack you, and sometimes this can just scare you and sometimes lead to serious consequences. He is always watching you and you know it. Do you sleep? Of course! But you can only do so early in the morning, from 4 am until lunch. At this time, Rain is not active and does not appear nearby... You made coffee and started drinking, sometimes glancing out the window, beyond which it was already dark. You really wanted to sleep... But you knew that you couldn't...
