well if one dies he will just be placed there again and again , until he/she manages to get the live done right. why do you think there are dejavues? just because you already have been there before. mostly those dejavues are to activate your senses not to make the same mistake again, which in you former live caused your death. for example if you once came along a murderer and he killed you. next live you will have a dejavue, keep an eye open and pass that hurdle. onto the next...

if you manage to get onto the next stage (like a butterfly during metamorphosis) i believe you are free. what you believed in live will happen. you can choose to go back on earth, you can just sit around the clouds and play cards with your buddies. whatever you imagine it will come true. you can be everywhere at the same time, as you will go back to where you once came from
