Come to Me-- I don't necessarily find those lyrics to be representative of a caretaker. She's saying, essentially, come lie in my arms and i'll comfort you *emotionally*. *tries to think of a type that wouldn't say, lie down if a person is exhausted* ? Of course, Si people can also say these lyrics.. but it's not what i think of when i think of si lyrics.
(What do i think of? mostly what seem to be random spew of aesthetic observation devoid of metaphor-- "blue and pink and green all over it" where we're inclined to say, "over what?" as opposed to "pedalling through the dark currents, i find an accurate copy, a blueprint of the pleasure in me" --physical examples, usually nature based, metaphorically describing an emotional state. Dude, its a blueprint of the pleasure in her. No guesswork, the metaphor is spelled out. Maybe I am talking about this so much because I have always cursed that I can't make the metaphors sound less obvious myself-- i cant write Si lyrics
But ... i think MOST of her songs don't even get ambiguous that much; instead it's just full on metaphors of physical states to describe how she's feeling. Plus a worship of Si. To me, that's Ne. An INFp or ENFj might use metaphors, but they're much more fluid and obscure, and who knows, maybe they seem so because I am not Ni.
INFp: "in an interstellar burst I am back to save the universe" -- not readily translatable
Ne person "he's away...im taking an aeroplane to follow my heart"-- physical situation used to describe feelings for someone
