A dreamlike and tranquil night sky, designed to evoke a sense of sleepiness. The sky is densely scattered with twinkling stars and a few delicate, drifting clouds, enhancing the depth and vastness. The setting includes a serene landscape, maybe a gently flowing river or a quiet forest clearing, under the mesmerizing starlit sky. The colors should be soft and soothing, with a palette of deep blues and gentle whites, creating a peaceful and calming atmosphere. --ar 9:16  --s 50
