I ruin parades. Royalty prefers me purple. The wealthy impersonate me with their money. What am I?

A celestial shape beneath the waves, I crawl along the sand and caves. With arms, but never meant to hold, My stories of the deep are told. I have no fins, no gills, no eyes,A twinkling creature in disguise. What am I?

I rock without rhythm, yet lullabies start, I hold the smallest cargo close to the heart. I travel no distance, but journeys begin, Where blinking new eyes first take the world in. I’m empty by day, at night softly filled, With dreams that are borrowed and futures yet built.

Sometimes I feel invisible but I know I’m sharp. It’s funny-we share a feature but you keep me away from yours. Some pass through me, some can’t find me and some can’t move me. What am I?

What is the global language that bridges speak?
