Create 4K dark forest scene with eerie stillness. Animate soft, flickering light source in center for mystique. Add light rain shower with glistening drops. Sway tall pine trees gently. Seamless looping transition. Studio Ghibli style: pastels, hand-drawn, fluid. Enhance with ambient sounds (birds, leaves, wildlife). Vary rain, light, and tree movement subtly. Optionally, include Ghibli-style character. Render in high-quality, loop-ready MP4/GIF.
