Interesting topic. What do you think about it, V?
My thoughts are this: if we are judged immediately when we die and then sent to our eternal place then when is there room for someone to come back and haunt?
Now, I thought I read somewhere (but might not be very credible) that it’s possible that after we die God lets some stick around for a little while to serve a particular purpose (like communicate sort of message). However I have no way of supporting that claim so take it with a grain of salt.
