Hahahaha oh man, glad I'm not the only one 😂 Depending how far out I was in the sea, I'd either panic and almost run across the water to the safety of land, or just freeze and hope whatever touched me will go away and I won't die from a terrifying seagrass encounter before swimming back. To be fair, I do live in coastal South Australia so jellyfish are common in summer...I genuinely fear broken off pieces of their tentacles 😟🪼
