Hyper-fast psychedelic anime flashback sequence. A vivid stream of memories rapidly cuts and morphs

Hyper-fast psychedelic anime flashback sequence. A vivid stream of memories rapidly cuts and morphs through surreal collage scenes. 90s Japanese cel-animation style, bold hand-drawn line art, vivid saturated colors, flat shading, sharp highlights, analog grain, chromatic aberration, high-quality sakuga motion. Every moment changes into a new visual idea: abstract city, melting room, spinning tunnel, symbolic objects, liquid backgrounds, distorted silhouettes, kaleidoscopic transitions, dreamlike anime cuts. No repeated illustration, no repeated composition. Constant motion: jump cuts, zooms, rotations, smear frames, impact frames, liquid morphing, rhythmic collage editing. Recurring motif: vivid pink iris with thick white X-shaped pupil. It appears as eyes, symbols, reflections, background patterns, and subliminal flashes, always clear and recognizable. Energetic, hypnotic, psychedelic, colorful, stylish, experimental. Not horror, not grotesque. No text, no letters, no logos, no subtitles. No realistic live-action, no 3D CGI, no ugly distorted faces, no gore. Keep it beautiful, elegant, intense, and animated.
