When my brother died, his body was marked at a very specific location. My culture will do this to identify the person's next incarnation.
After his death I was born. On the exact location they marked him before burial, I had a prominent birthmark.
Also I had relative who died from cancer tell me in a dream, that if you drink this you won't get cancer. He showed me a pitcher of water with lots of lemon wedgies. After this dream, I did research. And found lemons fight cancer in multiple ways.
Over 10 years ago, I heard in a dream, if you do good you won't have to transmigrate. After the dream, I got a dictionairy and found this word "transmigrate" means to reincarnate.
So basically in this life, we need to make it a priority to love, be kind, and help others, in order to end our birth cycles, and to live eternally in a heavenly like realm.
Why is this? Imagine if people with their own freewill still choose to be selfish and cruel to others? Would this place be "heavenly"? No? So we have to go through a training ground (Earth) to prove we can primarily with our own freewill choose to be loving, kind, and helpful to others, and even animals to a degree.
So why do you want to go to heaven, or what will it be like? From my research of NDEs, it's not going to be boring where we're playing harps endlessly on clouds, but will be more like the ending of Never Ending Story, where the boy gets unlimited wishes, and any and all dreams come true.
