Dan B vs Subconscious

i am reading in subway..... i daydream about running along the beach. Working so hard that my body heats up and my skin leaks sweat like a broken tap. I then daydream of running into the sea and the cool waves hitting my body cooling me down. Then my mind throws a shark into the equation without consulting me causing me to scream aloud and causing everyone in subway to look at me like i am mental.
