I haven't changed...

So suddenly the lights flicker in Arbies and on skyscrapers all around us. Half the lights everywhere stay off. Sirens go out, there's a giant voice being broadcasted saying to get to shelter indoors now. A black lady runs off screaming. I hear other little kids screaming and crying, I see people running away across a little park that was across from Arbies. I run into a skyscraper with my brother and we just start running downstairs. The scary part comes when I start hearing another little boy (sounded like Caillou from that kids show) crying and repeating "Guys! I'm not changed... really! Stop running..." mixed in with other little kids apparently crying because of it. My little brother starts crying and stops trying to run so I have to carry him. We keep going down stairs, they don't end. I'm frantic. I keep hearing loud footsteps and some little kid who's voice never seems to lose distance complaining that he wasn't "changed". It's nearly pitch black during this. While running down the stairs I woke up with my heart pounding cause at that time it felt like I was going to die and that usually wakes me up with my heart pounding.
