Have you ever wondered what "Exactly" happens when and after you die?

Have you ever wondered, What’s gonna happen when I die? Will I see a bright shining light? Darkness, then simply just forget your previous life, and are born a totally different being? Or, just… I dunno… just stop existing, like you just dont see anything your gone, you dont exist, you dont start anything, like a new form of human being, and your not born another person? I would love to hear oppinions from all beleifs. Catholics, roman catholics, Jewish, athiest, and I dont know any more, but all of those above that are in the catagory those are in. I think they are called beleifs.. Not shore
