The Killer

So I was hanging out with some friends last night, and for whatever reason, we got onto the subject of whether or not we sleep with the bedroom door closed. Apparently it's safer in case of fires? But it turns out that most of my friends keep their bedroom door closed because of concerns about The Killer, aka, a person breaking into their house at night with the express intention of murdering them.

For the purposes of this poll, "I share a house/apartment" is for situations where you have your own bedroom, but there are other people living with you; "I share a bedroom" is for situations where there is another person sleeping in the same room.
