What the fuck comes at night?
You gotta be shitting me. Why did they make this movie? What was the plot all about. What were they afraid of? And what in the bloody comes at night?
shareAt night comes the guilt of killing a whole family,
at night comes the realization that you have nothing to live for, after you survived by becoming a monster,
at night comes the understanding that you can not sleep well, as you failed to do what your moral was telling you to do.
It comes at night because you have nothing to distract you, nothing to do, nothing to care about, but just to listen to your feelings, which are nagging you, because you are not at one with your consciousness. Once the Sun sets, you see the starts, which were always there but you could not see them because of being distracted by the Sun. So, the Sun has set and now you see, the monster that you've become.
Hence the end, where they are up at night, the realization has came, and they can not sleep, because they see the monster that is inside of them.
