drop daydream and nightmare

Hey Hayley, this is a small MR that I meant to change in my peer-review edits.

This changes the intro language from:

Everyone needs access to clean water. The gap between water security and water insecurity can be the difference between a daydream and a nightmare.

to now: Everyone needs access to clean water. The gap between water security and water insecurity can influence people's everyday life. 

I tried to stick with something more neutral - let me know what you think. Thanks.
