You are trapped in your house. You hear knocking at the door. It sounds like this: *knock* *long pause* *knock*. You then...

I'd grab my trusty baseball bat, lock all the doors and windows,

None of these.
Find out if there even was someone at the door.
If there wasn't I'd check the rest of the house. If there was and I didn't know them, I'd grab my machete and think of a plan before initiating said plain. If I did know them, I'd grab my machete and ask them why they were doing that.

I'll look out the window to see who's there

Lol, u actually think it's the postman. Our postman actually gave me this idea, he always knocks so creepily.

Aw. What if it was just the postman?

Good for you, I escaped(granted I made this) (u killed him, u devil.>:) )

If you chose to ignore it, the front door breaks. A hooded man finds you and kills you. Same with attic.
If you open the front door unarmed, a bullet immideatlly plows through your head.
If you went armed, you catch him by suprise and slit his throat/beat him down.
If you escaped without food or water. you starved.
If you escaped with food and water, you made See More it to the local police station. The police track down the would-be murderer and arrest him. You may then rest assured you will not die today.
