..i'd rate that a 2..
my most recent nightmare,
a robot from space came to earth, and was taking names of people, it took one of my sisters, and mine..then..i guess the dream skipped over to another robot operated by a black and green alien , and began killing the people who's names it took..it sprayed a purple mist into their faces and the people exploded, so the next "scene" was me, my two sisters, and my parents in a room similar to my parents room and the robot was outside the door, which would mean it was in our house looking for my sister, it found us and wanted to take my sister, but my father begged it to take him instead...so it did..and it made us watch, thats when i woke up...
