You're suddenly awake. Your room is as quiet as it is black. For a moment you're not even sure of why you're awake as the only sounds you hear are those of your breath in the darkness and the silent rustling of your sheets. You blink a few times and turn to your nightstand to look at the clock. Three thirty four in the morning. You roll back into your pillow and close your eyes.
"What the hell was that!?" In an instant, every hair on your body stands on end and your senses become saturated with vivid life. You slide stealthily out of bed, your ears almost aching as they strain to hear something - anything that justifies what you just heard. As you stand there in the cold, by your bed, you become aware of a soft tapping, scraping, and wrenching below. Something or someone is working furiously at your sliding glass door downstairs - hammering into your home.
Without missing a beat, you open the drawer to your nightstand and pull out what you never thought you'd have to use. The cold, heavy steel sits menacingly in your hand and a soft click resounds and you turn off the safety. You grasp the gun like a knight wields his sword, ready to defend what is precious to him. In your case, it's your wife, who now holds a phone with trembling hands, and your children who you pray are still peacefully asleep.
You make your way downstairs, the shaking voice of your sweetheart fading into the background as she quietly pleads for help from the authorities. Every tiny fragment of sensation - the creaking of the floor, your shallow, frantic breath, the pounding of your heart - is processed a thousand times a second in your mind. Your thoughts weave and dart like bullet trains, astoundingly sharp, clear and quick. And yet, you can hardly think.
As you approach the sliding glass door you see a large, humanoid figure - the image of which sends a nauseating chill through your body. It suddenly stops moving. Time comes to a standstill, as your thoughts accelerate to a blur. You're unsure of whether or not you've been seen. The figure, with something in hand, raises it's arm. Acting in reflexive defense, you raise your weapon and fire a single shot. The figure falls backward, stumbling momentarily and then disappears into the night.
Did you do the right thing? Explain your thoughts.
