First of all this thread presented for those who believe this place indeed exists. Even though I am not a believer myself and an agnostic at the moment I want to share this idea with you.

After watching the movie 1408 I thought about this even more seriously and now I almost certainly believe it is this :
Hell is not a specially created place for torment but your own mind is hell itself.

Think about it, think of all the things you think disguisting and scares you. Now wait for a moment and imagine all the things you scare to think about and disgusting things pop into your mind without your control, whatever you do you cannot get rid of them, what kind of torment this should be ? There will be no escape from this.
Of course only way to do that will be to kill yourself. But now imagine this happens to your consciousness!
As we fed our consciousness with fear, after we die we may live with our sub consciousness where all the things we fear are there.

Same goes for heaven, it is a higher state of consciousness where you get rid of your sub consciousness and totally can control what you think and do.
