@Pinkie Pie Yeah, Idrk. If people believe in heaven and hell, then it could be. I don't, personally. But some people experience things after loved ones pass, and they're usually Christian, maybe it's wishful thinking/imagining.
I believe if they had a sudden and unexpected death then their soul might longer around for a little.. Like realising they they are really dead is not easy.. And those that knew they were gonna die (illness etc) move on faster, is not immediately.
