I definetely believe in ghosts, not only have i witnessed it I believe there is some scientific evidence that it is possible for them to exist for example, "Matter cannot be created, nor destroyed" therefore, even after you die there is still a part of you that can't die. When I was about 8 my grandma died but I didn't really understand it, mom didn't really say anything to me about it. one night I was lying asleep in my bed when I suddenly awoke around 3am-4am and the room got freezing. I could see me breath like you can in the movies and such. then my grandma walked into my room surrounded by light. me being an idiot little kid just started talking to her like it was a normal thing for my grandma to stop by at 3am I spoke to her for i think 30 minutes or so and then she told me to tell my mom that she loves her and she dissapeared. Still i had know idea of my grandmothers death at this time. The next morning, I told my mom about what had happened, she got all wide eyed and told me that my grandma had died about 3 days ago. since then i've always believed in ghosts and even seen a couple of others. idk maybe ghosts are attracted to me?
