Funny you should mention that. I read quite a few. Usually it will reflect the person's beliefs. Moslems go to Allah, Christians to Jesus, Buddists to Nirvana, etc etc.
It's true people who believe in one particular religion usually meet a religous figure from their religion such as Jesus,Mohammed,Budha, Isis, a Hindu God/Goddess,etc but...the idealogies they thought were literal ..they are told they are not. Perhaps God appers in this form so as a way of comforting them.
Such as the common themes from hundreds I have read:
1) A part of our consciousness is already part of the greater whole (God/Goddess) but while existing in the physical plane our consciousness also has a counterpart,the ego ,that tends to make us forget our true connection to God and the challenge is to eventually at some point realize it.
This would be considered new age,gnostic or blasephemous to the Abrahamic view of God being external.
2) There are various levels in the afterlife from the physical plane,the void (Hellish dark gloomy gray state..varying degrees of it),to the third sphere (first material level of heaven where most half decent people whether atheist or not end up. All the way up to the 10th level where from what I have read our individuality "dissolves" and we merge fully back into the universal consciouness of God.
3) The universe has undergone several "big bangs" and has existed for much longer than 13-14 billion yrs.
4) God created the universe as a way of exploring he/she self thru the multiplicity of multi-trillions of events occurring at any one given time.All of us and everything in the universe is a small part of God. Even God does not fully understand what he/she is so perhaps in that sense even God is limited.
5) Gods two main rules are to be selfless and to practice uncondtional love to each other,to God and to all around us. Most religous scripture other than these two main themes amounts to no more than commentary thru the eyes of the people who wrote them and with all their cultural bias and prejudice,either personal or political.
6) Hell is not eternal. We are held to a standard when we die..how much love we have within us..our intent, and according to that we fit in where we can in the afterlife. People who have committed horrific deeds end up in the void for a period of time..untill they realize the error of their way, God will then allow them to move up thru to the next level.
7) The Devil,Satan does not exist.It's the absence of God that correlates to the concept of darkness,evil,bad intent. God would not create a confrontational being to oppose he/she.
8) God is eternal because God exists in it's true state of one not bound by the duality or force/counterforce of the physical universe.
Just a few of the commanalities I've seen.
Or, how open are you to the idea, that these are the final throughs of the human temporal lobe, gathering up the person's life experiences, stored for this event to give that final dream before cold, dark, oblivion?
Yes, this could be the case. I cannot know for sure they are real. If my consciouness just evaporates upon death I can't get too choked up about it because I will not even be self aware anymore so how could I ever regret not having an afterlife. *lol*
