Short soundfile I created using Logic Pro.
Imagine the following situation:
1. you wake up in alone in the desert, slowly open your eyes and scan a desolate landscape
2. you begin walking towards the nearest hill, and as you reach its peak you see a waterfall and a river and begin walking towards it
3. because you are very hot, you happily jump into the water and begin splashing around
4. suddenly, you see something come down the waterfall, grab your leg under the water and try to pull you under
5. you begin fighting noisily with the unknown thing and eventually you free yourself
6. you start swimming down the river not sure where you are going or what you are running from
