I know its morbid...But im scared of dying now because? I keep having these dreams of my future funeral? Is this real? I saw a orb spirit orb in it and it said its name was the usher i saw my funeral like i was there... Im 14 im scared of dying? Has this happend to anyone because isee all this darkness moving in my room im not really religious but i do believe in a afterlife? Heaven or hell i hope its not bad? Its like all this darkness and moving things idk im just probably going nuts from the sickness but idk?
