The Hollies's song "All The World Is Love" is about the songwriter's state of mind when he is feeling disconnected from the world and lost in his own thoughts. He values things that are hard to find and feels like his mind is gone somewhere without a care. The lyrics suggest that the songwriter finds solace in writing down his thoughts on paper and building imaginary castles in the air. He wishes his mind could be as clean as the blue skies and white clouds above him. Even in a crowded room, the songwriter feels alone and disconnected from others. He has left his mind somewhere behind him, drifting in its thoughts. The imagery of bubbles forming around him and leaving his body on the ground suggests a feeling of weightlessness and detachment from reality. However, the songwriter concludes that despite his isolation and detachment, "all the world is love." The overall message of the song seems to be that even in our darkest and most isolated moments, we can still find love and beauty in the world around us.
