Have you ever wondered what makes the hairs on the back of your neck stand up?

Have you ever heard faint music from another room, only to find that no one is there?

Have you ever realized your cell phone charger is missing, despite the fact that you're certain it was plugged into the wall?

The good news is: it's Nas.

The bad news is: it's Nas, and he's in your apartment, taking your stuff and whispering at you.

In a new video for Funny or Die, the rapper serenades a victim of his smooth home invasion skills... that is, if you believe he was ever there at all.

Check out the video.
