The Horrors' song "Sea Within A Sea" is about the journey of life, the struggles and challenges that come with it, and the hope for something beyond the limitations of our current reality. The lyrics suggest that some people feel alone and vulnerable, walking on a path full of obstacles, without any sense of safety or refuge. The sea is used as a metaphor for the unknown, the mysterious force that governs our lives. Despite the darkness and uncertainties, the song encourages us to keep going, to follow our dreams even if they seem impossible to reach. The sky is presented as a symbol of hope and inspiration, a sign that there is more to life than what we can see with our own eyes. The song also touches upon the idea that as we grow older, we may face new fears and challenges that we never anticipated, but that it's important to keep pushing forward and not give up on our dreams. Overall, "Sea Within A Sea" is an introspective and reflective song that calls for us to be brave, to face our fears, and to believe in ourselves even when the path ahead seems uncertain.
