When Jane heard the scream, every ounce of color draining from her face. Jess.  She had known her as well as everyone else on the team.  Even if that wasn't a lot, they were the only people she knew now. Jane felt her mind slip out of her skull, as if it had decided to take a step back and watch what the body would do without a brain to control it. The answer was not pretty. At first, Jane simply stood there, frozen, like a statue. Jane felt so detached from her body, unable to control it, only able to watch what it did. This had always happened, even before the outbreak. A doctor had said it was some sort of defense mechanism against fear.  Some sort of selective depersonalization they had called it. Whatever it was, it happened when Jane was absolutely terrified.  Not the standing up and talking to the class kind of terrified. The kind of fear you get when you're getting attacked, or are being chased, or sometimes...when you hear a scream.  That had been what caused it to activate this time. After about a minute, she broke her frozen state and threw herself towards the edge of the roof. Her body stayed on the roof, while her head poked off and was gazing at the ground, several feet below. Right then her mouth opened and puke spilled to the ground. Not much, due to her lack of food and water, but a little, about how much could fit in small water bottle. She lifted her head back up, resting it on the edge of the roof. Her vision was hazy, but she could definitely see a few moving blurs in front of a much bigger yellow blur. She silently watched them, mouth open agape, eyes droopy.
