I have no idea how to interpret your prophet's words. That's for you to do. He's not my prophet.
In Hinduism, individuality is lost what Atman finally becomes Brahman, and before that, the soul body finds a new physical body repeatedly in the process called reincarnation.
So you'll still be trapped in another physical body in this world while I'll still be me but like a bird free of my cage to visit and experience all the worlds of God?
I dreamt once I died and I wanted to travel but didn't know how as I was just suspended in the air. Then I sensed other beings and they telepathically told me just to think or imagine and I would be there. So I thought and I was there. It was thought travel and quite possibly is our way of getting around in other worlds.
But the one catch. And here is where justice comes in for all of us. If we don't lose our identity then we must face up for eternity to our deeds and acts in this life. So for some that would make them feel happy forever but for others, miserable living with the realisation one may have done some evil that can't be undone.
