Water is in the walls, that's where it comes from, and if you put a hole in the wall, it will rush out and drown you. I think I got this from an episode of Incredible Hulk where they were stuck underground and water was filling up the room. Also, from Amityville Horror (I didn't know it was blood). My dad was about to drill a hole in the wall and I started crying and begging him not to do it because we would drown!
