If there is a bigger picture, what is the impact of you ceasing to exist?
If we think of the universe as a large, changing pattern, is there always a pattern defined by the sum of all consciousness from which viewpoint each part of us is akin to a cell (maybe a neuron?) in which case your individual death is meaningless
on some higher level of complexity and self-awareness?
Have you ever passed out, and it seemed as if no time had passed for you at all while others saw you not moving for several minutes?
Now imagine never coming to. That is annihilation.
From another perspective, could it be like (and I know the following metaphor is a very rough one but it’s the most intuitive way to put it so bear with me) waking up from a dream?
