Underwater

In english classroom I had to write a gothic chapter, so I decided to make this short story.
•
I didn't give any name or gender to the protagonist. Let your imagination create your own character, or would you embody it?
•
A story which is dealing with a inquiry about drowned people each 11th of february.. Rainman family, their mansion and the strange city of Riververn.

Sorry for my mistakes and my low level of english.. If you could correct me, it will be nice. If not, good luck and tell me what you believe of this :)
