You Guys Are Writers, Maybe You Do This Too?

Do you ever write the future in your mind? Like, for example, I've been crushing on this guy and so I'll sorta day dream about how we tell eachother or how we have our first kiss. But it's not just good stuff, it's everything. And, anyone who knows me knows I'm never in reality persay. I like my own world where everything is sparkles and unicorns and happy endings.
Anyway, I was just wondering if it's a writer thing or if my mind hates my guts and decides to torture me with optimism and a great imagination. The first one would be better considering that it would suck to have my mind hate my guts but anyway, please tell me if you do or don't write little one shots about nothing in your head!
