You're up late. Working, studying, watching a move, reading on the computer. Doesn't matter what you're doing, it's the feeling you get. You're tired, your eyes burn and have the gritty feeling you get after not sleeping for a while.
You finally decide its about that time to go to sleep.
You are almost asleep, then all of a sudden you are falling. Like stepping off a cliff, you're in free fall, though your body isn't even moving.
Then, like a bungee cord snapping back, you jerk awake, heart thumping a little faster, blinking quickly, wondering what just happened.
Doctors call it a hypnic jerk, a natural reaction, they say, to your brain thinking you're dying. When your breathing and heart rate slow down that much as you fall asleep, your brain gives you a little check up.
Just to make sure.
What the doctors don't know, however, is that your brain is right. Every time you let your self nod off and get that "falling" sensation, you are not falling. You're being pulled down.
And one day...
Your brain won't be able to pull you back up.
But, worst of all.
They will finally have you.
