You wake up. You're lying on a bed, on your back, in the middle of a pitch-black room. You don't know who you are. You don't know where you are. You don't know why you are there. All you know is that you are completely naked.
You get off the bed and land on a pile of soft things.
They may not be your clothes, but you put them on anyway.
Suddenly, you hear footsteps coming from somewhere, and you somehow think that they are coming for you. You start to panic, not knowing what to do.
