Is there an English word or idiom that describes a person who's blissfully unaware or oblivious to their surroundings? I always thought this word was "aloof," but "aloof" seems to hold a rather negative connotation, whereas the word I'm looking would almost connote a positive, like "living in a fairy tale" - or something along these lines. Is there a word for this, or is "oblivious" as close as we get?

    What's wrong with bliss? "informal: reach a state of perfect happiness, typically so as to be oblivious of everything else." "blissed-out hippies" –Google

  • I'm confused by this question. You used an idiom and the exact word as part of the question. Surely the answer is simply yes
