I often have a nightmare where I am older and fall, but I can't get back up. I scream and scream, try knocking on the floor and walls, but nobody can hear me. It feels so insanely real, and it even takes a lot of time before I wake up. Being alone is hard, but most people truly don't know how dangerous having no one can be. Whenever I read that an elderly was found after months because the neighbors couldn't stand the smell, I hope I won't be that person one day.
My greatest fear is people. The amount of evil people are capable of is insane. The more you dig, the worse it gets, and it never stops.
Oh, and spiders. I love all animals, but spiders just freak me out. I know it's not their fault.
