I used to be so scared of the dark that I wasn’t able to walk into a dark room in my house without serious planning and at least some kind of weapon. Usually it was a particularly nasty looking knife my mum used to cut open packets of rashers with that took my fancy, my thinking at the time basically centering on the fact that if it could cut rashers, it would cut vampire flesh just as well. I slept with the light on till I was about 16, and sporadically after that until I was about 20. To this day, I sleep with a hefty black torch within grabbing distance to keep the cold black air in front of my closed eyes from twitching. It usually works.
