A little while ago I was sleeping in bed, in the early morning. My mom and my sister, being crazy, were awake at the ungodly hour of 7AM (!!).
You know how stuff from the real world can enter your dream, kind of like in Inception? Well, my mom was yelling bloody murder at my sister to hurry up or she'd miss the bus to school. My mom's got quite the vocal chords, so of course her screaming entered my dreams, and with the way she was screaming (a sort of blood-curdling high-pitched wailing sound), I for some reason got the impression that the house was burning down in my dream.
When you're just about to fall asleep, you ever dream that you're falling, and then, just before you hit the ground, you twitch and wake up? That's called a hypnic jerk, and that's kind of what happened in this situation... except more extreme. The sound also woke me up, and, just like in the hypnic jerk, the dream carried on into real life. I leaped out of bed, flung open my door, and dashed down the hallway.
I sleep naked.
Thankfully, by that time, everyone had already left the house. And I also managed to clear my head and realize that it was a dream before I ran out the front door.
I've never experienced anything quite like it.
