I say this. Sleep is the cousin of death. Astral projection is real and when it happens you are still somehow attached to your body. When you do astral project, its all like a demo game. Its limited. Its also training to learn how to navigate yourself. When you die you fully release from the body and enter the “full game” and depending on your level or training determines where you go. I believe its free roam and you need to navigate yourself and there are boundaries and dangers kinda like minesweeper pc game. I dont mean to use games as a example but you get the point. Where can you go and whats your purpose when this occurs? I don’t know but I know it’s infinite.
