Well, someday soon I'll be taking beliefs with me to war that just won't allow that. My Christianity says once someone is dead, they do not come back or communicate with the living. There was a time when this was not taught, and it caused problems ie) the historical 'cult of the saints' and whatnot.
I hope you have researched what you have come to believe well, because too many people I've encountered make spiritual decisions carelessly.
I do not know your background, and I do not want to get into a big argument, but I can predict the way some will react to your original post. They'll consider what you've presented nonchalantly, continue in their religious ignorance, and then one day they'll realize how near death may be, and loose their resolve.
I take this stuff seriously.
Perhaps you could elaborate on your beliefs, and put what you've suggested about dreams into better context.
