This sesquipedalian need not be. However, I wanted to make a long word because I had never made one before. And ever since I saw Waking Life by Richard Linklater, I was fascinated by the idea of lucid dreams, to be completely conscious while asleep. What a beautiful thing.
Cohesion brings together the strengths of individual entities to form a better unity. The bond between somnambulist meaning “sleepwalker”, and lucid from the Latin lux meaning “light” or “clarity”, along with the suffix -arian (having a concern or belief in a specified thing) has allowed this word to flow without effort. And that’s how this word came to be.
