"...the thingness of something becomes apparent when it is no longer functioning as it did before or it becomes dysfunctional or if it appears in an unexpected place..."

ok so i am dying and you put headphones on me so i hear the sound of someone repeatedly saying : banana pear apple? so that if i don’t in fact die you can ask me if i remember the names of any fruits being said to me when i nearly died? can i have an advanced care directive that specifically requests you not to do this?
