conversations in my brain?

......"See I'm paranoid, but in this weird way."
"I don't get it."
"It's just off, you know. Like last week I was taking my dog for a walk, well it's not really my dog. It's my brothers, but he's in school. Anyway this girl backed into my neighbor's driveway, and she didn't look like she would do anything incriminating or anything like that. Anyway, as I was walking my brother's dog closer to the car I just imagined me walking past it and her pulling out a gun and shooting me, so I crossed the street, just to avoid walking directly in front of it."
"Well did she have the windows down?"
"What?"
"Did she have the windows down? If she wanted to shoot you she'd probably need the windows down, unless she's want to shoot you through her window."
"Well yeah I guess that's true. But isn't it weird, the way that I'm paranoid?"
"Not really. It just sounds like your normal paranoid."
"Well that wasn't really a good example. I'm bad at explaining things. Like sometimes when I'm falling asleep in my room, you know how my room is secluded and I can't really hear anything because the heater gets to be so loud, and all?"
"Yeah."
"Well sometimes I imagine that the zombie apocalypse is just starting and there's a zombie in my house, and it's already infected my parents. So I freak out and go make sure all the doors are locked."
"Yeah, it sounds like you're just normal paranoid."
"I guess so."
