heres another one

the water here is about 40 foot deep, i think, it's hard to judge distance, but i tried diving down on a breath and got nowhere near the bottom lol, i felt my mask pushing onto my face, and my ears popped lol, and later that evening i was just talking to someone and my nose felt like it was bleeding, i looked down and though it was snot lol, but it wasn't , it was just sea water !!!!! pissin out my nose !!! happened 3 times that evening, anyone heard of that before ? has it gone in my ears or summat ? I just leaked sea water out of my nose about 3 hours after i went snorkelling about 12 foot deep ( no idea of actual depth lol, just a guess)
