you'd be in the forest and you came across a spot that looked like a really deep lake.. Then all of a sudden something..or someone rose from the deep water.. They were at least 10 feet tall.. And looked probably taller..the being would turn and stare at you

"..I don't recognize you.. Who are you.. Answer now.."

he'd have a voice that made it clear he was slightly annoyed.. Maybe busy? Or looking for something.. Maybe you should answer him.. But its up to you
