Lama Ole’s answer:
The only thing that can die is the various ego obstacles, obstructions, and blockages. And if you dream of corpses, and so on, then it often means that you are currently achieving certain special abilities.
What is dying is the old incrustations—the stiff ideas and the habitual thoughts, the ego trips. And when those fall away, it is like cleaning a light bulb or a mirror: more and more of the light and the strength, which exist on the inside anyway, become visible. And after waking up, you feel good and are quite wise.
