Write a short story set on 20 May 20, ending with the revelation that it was all a dream.

Here is another example story:

On the morning of 20 May 20, Elara awoke to find herself not in her bed, but in a lush, bioluminescent jungle. Giant, glowing flowers pulsed with soft light, and the air was filled with the gentle chirping of unseen creatures. A tiny, iridescent dragon, no bigger than her hand, landed on her shoulder and nudged her towards a shimmering path. Following it, she discovered a hidden waterfall that flowed with liquid starlight, leading to a city carved into the side of an enormous, ancient tree. The inhabitants, small beings with wings like butterflies, greeted her as a long-awaited visitor. They told her she was destined to restore the lost melody of their world. Elara spent what felt like days learning their songs and dances, feeling a profound connection to this magical place. As she sang the final note of the restoration melody, a wave of warmth washed over her. She closed her eyes, and when she opened them again, she was back in her own room, the morning sun streaming through her window. The date on her calendar still read 20 May 20. She smiled, the echoes of the jungle's melody still in her heart, knowing it had all been a beautiful dream.
