Dear Horror Lovers,

We're currently in the process of producing a psychological horror set around a lake.

Contact with the lake's water does not prove fatal. However is does have the tendency to gradually change the characters' personalities.

We have been searching for plausible physical manifestations on the body caused by contact with the water.

Originally our idea was to have a black mark appear on the skin of every character that comes into contact with the water.

Here's our question: What would be a more original, nastier manifestation? Any ideas on how to show the water's effect? For story reasons we must visually see the water's effect on the body.

Any suggestions are deeply appreciated and may lead to closer collaboration in the finalization of the film, including mention in the Special Thanks section of the credits.

All the Best,

LeAuguste
