I wanted to portray how each word becomes extinct:
Idea, bias, feeling, vogue, existence.
These five words are disappeared and reappeared in our mind and society. Therefore, they are not completely disappeared but might be disguised, and when the surrounding environment has changed, they become visible.
The words, feeling and existence are shortened as "feel" and "exist" for the sake of better composition.
