Don’t go off by yourself to investigate a strange noise.
It’s one of the most basic horror tropes there is, yet, there’s a little bit more to it than a simple plot device to arrange a meeting between a disposable character and a suitably entertaining instrument of death. Think of the other basic horror rules. They don’t seem particularly daunting in real life. Rarely, if ever, does anyone think twice about doing something like drinking a beer or saying “I’ll be right back.” That’s because we know that, rationally, there is no connection between doing those things and issuing some kind of implied invitation to a masked psychopath or otherworldly beast that craves human blood.
On the other hand, a lot more people will hesitate before descending a staircase into a darkened basement to fix a blown fuse, or getting out of bed to check out a noise from the other room. The sense of fear that accompanies confronting the unknown taps into something more primal, namely, that you don’t know what will be there when the lights come back on.
