Your descriptions are all conjecture based on... what? Think about what your concepts of a so-called 'next life' are based upon, and why you have a need to maintain such ideas.
The point of living is here, now, not in some imaginary future. THIS right in front of you is what is real. Live it, fully and completely, so that you are fulfilled NOW. Then you will be ready to experience the next moment as it unfurls, without any concept of what it will be, without any expectation of reward, which only spoils the experience. As long as you continue to nurture fantasies, you will never awaken to the rich life you have already been given to live now. It is already complete, so there is nothing to 'get'; no 'heaven' as reward for 'good moral behavior' or hell for 'evil moral behavior'. Those are merely imaginary concepts we like to stoke the fires of to serve our egos. When the ego dissolves, there is no more self to gain or lose anything. There is only this complete eternal Present Moment, as it has always been, forever and forever, and it is quite sufficient. Anything else pales in comparison.
Only when you completely empty yourself of all of your beliefs, concepts, and opinions about what reality is, can you be fulfilled, and fulfillment can only occur in this present moment. It is nothing that you can imagine, no matter what you may think.
You are already a unique person, but underneath, that uniqueness, you are the same as everyone and everything else; Nothing Special. Just become who you already are and that will be purpose enough. What more do you want? You can't even handle the present moment, let alone any 'next life'.
If you think you are only a unique creation, without any shared common substance, then yes, you are a complete fraud.
You are a lie unto yourself if when you look into the mirror and see something you only imagine to be who you are. When you at last see that you have been an actor who has taken the role he has been playing much too seriously, you might enjoy a good laugh at your own expense, and then proceed to wake up from your sleep to discover who you really are. It is then that the real excitement begins.
The fact of the matter is that you know nothing about any 'next life'. All you know for sure is that you are here, now. So if that is the case, then you should proceed to actually be here, now. Anything else is delusion. The past is dead; the future non-existent. All you have...and I mean ALL you really have...is what is right in front of you now. It can be gone in the next moment. Live it before it is gone forever. So what do you propose to do?
Think of it this way: that the Divine Essence is playing all the infinitely diverse parts of the universe all at once, and those parts include you and I. It is playing each one as a unique manifestation of itself, but beneath all the masks, it is the One Divine Essence playing the exciting cosmic game of Hide and Seek with itself. What could be more compelling than that. Just get with the program, but never forget who you are underneath the mask, not even for one moment.
