夢層

[Instrumental Intro] [0:00-1:05, very quiet low-frequency drone slowly rising from silence, wet underground atmosphere with distant ventilation hum, sparse metallic creaks and faint dripping water, no vocals yet, only subtle breath sounds at the end] [Verse 1] [1:05-1:35, haunting female vocal enters very distant and breathy, heavy reverb and long delay, whisper-like, almost inaudible consonants] 消えゆく街の　残光を 抱きしめて　落ちてゆく [Short instrumental break with soft humming] [soft wordless “aaaah” humming, layered thinly, drifting in the space] [Verse 2] [1:35-2:00, vocal slightly closer, more emotional, still heavily reverberated, gentle vibrato, slow sub-bass pulses underneath] 地下の夢が　私を呼ぶ コンクリートの　冷たい腕に [Build-up section] [drone thickens, sparse water drips and distant train-like rumble increase subtly] [Chorus / Climax] [2:00-2:40, vocals rise in intensity, 3-4 layered harmonies, wider reverb tail, slight pitch bend for ethereal feel, dramatic yet restrained] 忘れられた　名を　囁いて 影が踊る　果てない回廊 もう　戻れない もう　戻らない 夢層の底で　永遠に [Heavy swirling delay and echo on the last line, voices overlapping slightly out of sync for ghostly effect] [Outro] [2:40-3:20, vocals gradually move farther away, volume fades, only echo tails remain, drone slowly thins out] …夢層… …夢層… [Final 10 seconds: last vocal breath dissolves into low drone fade-out, end in near-silence with faint residual reverb]
