well, i would like to think that something that i would like would happen. when you said there was no proof, you hit the target. there is no proof, there wont be proof, and there will never be proof.
i think, that as you go through you life, you gather what your perfect and most imperfect worlds would be like. if you see an amazing landscape, i think that would be in your paradise, but your worst nightmares would exist in your hell. i dont think you are judged by any one person, but i think you are judged, based on how you would judge yourself, and what you did in your life before. so, the only harsh punishment you would recieve would be no worse than what you would give yourself. so, if you, unbaised, felt that you had been a good person, you would go to a 'heaven' of your making, if not, well, there is the alternative...
i dont think your consciousness can go away. do you know that little thing inside your head that is you? that thinking part of you that tells or shows you what you need to do? the thing inside your head that makes sense of the world around you? do you honestly FEEL like that could just dissapear? do you feel like it could go away and not exist anymore? i cannot make myself think that it could simply 'go away'
i have done the same thing you have. sit there, and wonder about the universe, all that is in it, their purpose, their destinies, and the 'after' that everyone neglects to mention. the only difference is, that i dont look for 'proof', i look for a meaning to it, or i look for a feel wheather i just 'feel' that it is true or not. if i may, a piece of advice to you, is to just let the world take you where you feel you need to be. go with what you feel. and, i would not worry too much about an afterlife, because, the only way you will know is to be there. dont rush what is not meant to happen right then.
good luck, and have a great day!!!
