"When you need to wake up"

You’ve just woken up after a fair night’s rest and look at the clock. It’s 7AM as expected. You push your groggy self into the sitting position and eventually stand up. Your legs wobble underneath you for awhile as you walk down the hall in pursuit of coffee.
The hallway is lined with huge windows on either side. You’ve always felt a bit paranoid walking down the hall at night. Someone could very well be watching you. Even though you know it’s highly unlikely because you keep your curtains shut at night.
You stop periodically to open a few of the windows and let the morning sun in. “The next best thing to coffee is the sun itself” you often think.
As usual the curtains open without a problem and you’re left with a rather striking view of the sunrise.
Everything is normal as always.
That is until you hear a tapping noise. It sounds like something’s tapping on one of your window.
Your mind plays with the sound and starts coming up with some terrifying ideas as to what it could be. 
After some thought you decide the best course of action is to face the noise head on. It’s probably just a tree branch anyway. Plus, maybe this will stop your mind from wondering like it’s been lately.
The coffee was soon forgotten when you make your way back to the hallway. You examine the windows one by one.
The first set of windows was cracked, but only slightly. 
That’s odd, they were both cracked the same way on either side of the hallway.
Curiosity killed the cat, you went to the second set of windows.
They appeared to be fine. You want to walk away but something flickered in the corner of your vision. 
You quickly look toward the thing hoping to catch it in your sight before it goes away, but it’s gone. 
You think it over for awhile while looking out of the window. It was probably just an animal.
All of the sudden you hear screaming. This horrible ear shattering noise knocks you back into the other side of the hallway. 
A face of a masked person flickers in and out of the window which has now darkened as if it were night again. This makes you highly uncomfortable for reasons already explained. 
The screams turns into words. “WAKE UP WAKE UP” 
It feels like the person is screaming in your ear. 
The screams get faster and turn into more of a whisper.
"WAKEUP WAKEUP WHYWONTYOUWAKEUP"
You’re not sure how long it’s been until your mother calls your name for breakfast.
You blink and go on with your day as usual.
On the brightside, now you’re awake.
