The story in my mind right now is, in my opinion, one of the coolest stories ever. Which makes sense. It was designed specifically for me to enjoy. While I daydream, there is a small part of me that is simultaneously fangirling.
I've thought about writing my daydreams down, but they're WAYYYY too complicated, and contain tons of characters from books and TV shows that already exist (and would be difficult to disguise as original characters). Changing that would ruin the story for me, though.
I've told my dad about my daydream storyline (and I inform him of any new developments), but I rarely am able to go into very much depth.
Sometimes I wish I just had someone else to geek out with about the TV show in my head, but there is no one. I am a fandom of one.
