Mr Nightowl is about an insomniac who can't get to sleep with unfinished thoughts in his/her brain. In my case completing a song. At times a guitar riff/melody or lyric pops into my head as I’m starting to doze off.It could apply to anyone with unfinished thoughts/business on their minds. For me “Mr Nightowl” is planting the idea to try to stop me going to sleep that makes me want to finish it off by staying up. The lyric that sparked the inspiration for the song was in the chorus when I sing, "I need to break this cycle, in hope to put my mind at ease".
