AFTERLIFE .... a big ?

So i was watching a supernatural horror flick about ghosts, how and why they communicate with the living .. the usual stuff and it got my thinking about AFTERLIFE. I have read and blogged previously about Afterlife or the life after death but that was more from a spiritual point of view. What the Yogi philosophy tells us or what we as Hindus believe in or what the other religions like Christianity have to say about afterlife and resurrection, etc .... but lets pretend for a second that we haven't read anything or have no reference .. in such a situation what would your views be about afterlife. Would you believe that we just disappear after death or that the souls just roam the earth in search of some medium to communicate with their loved ones or that we are just reborn, only the body perishes but the soul remains iternal ?

I personally have always believed in the supreme being. oF a higher power who guides us all. But then again if you believe in God then you have to believe in the Devil. The good cannot exist without the evil, the sun cannot rise without setting first, there cannot just be ups and no downs ...every coin my friend has two sides to it.

Just some fodder for the mind. I wish one day i would get a chance to devote a lot of time in researching the paranormal, the occult. After all don't we all want to know where we would be after this life. What the Afterlife would be like? Would it be black or white like heaven and hell, or would our Karma in this life decide what our afterlife would be like or would we be reborn each time until we achieve the highest spirituality or worst just hang around the living hoping to be able to communicate.
