Horror beyond belief

My grandpa was a merchant navy officer for the majority of his life, and spent many days at sea.<br>He would often tell stories of the deep sea, and what he experienced while he was out there. He used to say that the most deadly thing you could do was go into the waters bathroom late at night, and stare out the small window above the sink.<br>He’d always say that whatever was out there, was watching him, and that he felt it whenever he went to that bathroom late at night.
