Have you ever had that sudden sensation of "why am I doing this?" sneaking up on you? You know, that kind of feeling where some common practice, you were so accustomed to in your daily routine that you never questioned it, all of a sudden seems to be totally absurd and pointless to do? Like, for example, washing your hands after using the toilet, closing the faucet and realizing that you opened it with supposedly dirty hands and now are touching it with supposedly clean hands, potentially picking up again what you deposited there in the first place?
