夢であの世に迷い込み、忘れられない友達ができた

In the near future, where lucid dreaming (controlling your dreams) has become possible, a world I visited on an ordinary night was a mystical town that looked just like the Heian period of ancient Japan. The residents of this town say that no living person exists here. Is this experience while sleeping merely an illusion created by the brain? Or is it...? Is it a dream, reality, or an illusion? Although the truth remains unknown, this is a story of youth deeply engraved upon the soul. ーーー All visuals in this video are generated using AI.
