you were on a walk in the forest. It was dark out..

you were very cold and you decide to find something to drink before you die from dehydration.

you walk around the forest for a while, but then you find a lake. You go to the lake and it looked pretty dirty, but it's better than dying from dehydration.

you use your hands to get water out of the lake to drink, when you see something large in the water, staring at you. It looked about 50 feet long..
