Existential dread is a feeling of anxiety and fear that arises from the realization of one's own mortality and the uncertainty of the world around them. It is often associated with the philosophical movement of existentialism, which emphasizes the individual's freedom to make choices and take responsibility for those choices. The term ANGST, which is a 5 letter word, is often used to describe this feeling of dread. It is derived from the German word ANGST, which means fear or anxiety.
