This sense of dread that comes with a sense of the dissolution of all beings along with oneself was for Heidegger a metaphysically potent state, for in effect one gets a foretaste of one’s own death, a sense of one’s being annihilated, a sense of going into nothingness—and thus a sense of getting to the metaphysical center of Being.
He's hinting at a lot of what some Eastern traditions have tackled differently. IT doesn't have to descend into dread, it could be Enlightenment in the Buddhist sense.
