You're a man named Danny, who just recently woke up from a coma. You don't know what's going on or what has happened, nor do you know how you got into a coma in the first place. Your best friend, Dennis, has visited you a couple of times while you were in the coma. He has left you a letter, trying to help you memorize what has happened. However... you get this strange sense that something has happened to him. You also have a strange feeling that something is watching and controlling your every move... What can all these senses mean? Not only that... but the home you live in... is cursed.
I know it doesn't look like a Sewer -_- sorry. But it's a room with water, so I just named it a Sewer :P Unless I make up another name for this room...
