You carry on dozing
From Create Your Own Story
Not bothering to look up and in a semi asleep state you hear the light footfalls head towards you, pause at the edge of the pool and the russling of clothes. Followed by splashing as they step into the water.
Then all goes quiet until you hear a short gasp. It seems whoever it is has noticed you.
You half expect to hear them gettin up and leaving the pool but that's not the case, instead, nothing happens for a while before you feel something lightly prod your thigh.
