Is it called "no castle" because the castle is actually John Travolta in disguise? Or was he just in fhe castle and the title is meant to trick the viewer?
the title was based on the music. the music existed before the video, and the title for that music is 'no castle'.  That's because the music seems to have a feeling of "no", fortified into an entire castle. Imagine an entire castle of no. Then, later, a video was made, to reflect the music. I should clarify, that the music also seems to have a twist ending, which arguably may have turned it into a yes castle, but i tried to leave that open for the listener to decide
