Goddamnit I feel so dumb.

I was watching someone do a playthrough of one of those jokey horror games where they take the piss out of things but it has the player knock a door at one point. Fucking gave me a heart attack as it sounded like someone knocking on my rooms door when in reality it was just a fairly clear bit of audio that played in one side of my headphones, the side my doors on to boot.

It got me twice and I feel like such a prat.
