Existential angst
From Tardis Wiki, the free Doctor Who reference
According to K9 Mark I, talking to someone with the same name as oneself could give one a feeling of existential angst. (PROSE: Jealous, Possessive) Existential angst was related to existential crises (PROSE: The Avant Guardian, Lonely) and existential despair. (PROSE: Snowman in Manhattan)
Behind the scenes
As is evident in the name, existential angst is a concept in existentialism.
