So when I was a teenager I used to have a desktop computer in my bedroom, with desk, chair and all, the bed was against the far wall from the door, with the desk in between. One night I woke to a dark figure bending down over me while I slept, and my instinct was to punch it! And I kinda hurt myself by hitting the metal frame of my computer chair which I had somehow rolled next to the bed without noticing, with a black hoodie draped over it.
