SCP-4999 has always been a favorite of mine, purely because the thought of dying all alone, no-one to help comfort me in what would probably be the scariest moment of my life is very probable honestly, and the idea that someone, someTHING in the universe would show up, as someone to talk to, someone to just BE there at the end for me, with no desires than to ease me into the long night with warmth and comfort... it is something that, if possible, would make me eternally grateful
