I'm more of a science guy so when I hear stories like the original poster I usually say something like.... well its Halloween, tons of people running and and down the driveway blah blah blah. But at the same time if that give you comfort than who am I to rain on that parade because until you can rule it out as a possibility it is one in my books.
Is there a spiritual afterlife..... possibly, physicists theorize that there are other dimensions so perhaps moving on to those dimensions is the after life. As for seeing into other dimensions sometimes it can only occur when looking at things just the right way.... e.g. ghosts. An analogy might be looking at a sheet of paper..... easy to see when the flat side is facing you but difficult when looking at the edge.
Other ways of thinking about the after life might more do with your legacy..... memories, deeds, genes you've passed on.
On an atomic level when you die and decompose your atoms get recycled.
So maybe there is..... it's just probably not a bunch of fluffy clouds and do gooders hanging around.
I'm hoping for a waiting room with TV so real it's like you're there, a couch so comfy you never have to shift, and every woman I've ever whacked off to is there offering bb everything at no charge...... oh yeah and a fountain of unlimited mineral oil........
Okay fine I'll settle for my friends, family and world peace.
