last night i dream that my stepdaughter lost half of her arm, it was very disturbing when i wake up, i was afraid to fall asleep again, i never dream about my stepdaughter even i'm a good dreamer.
Very difficult to say. I once dreamed that I lost a finger and the very next day it got slammed in a car door, but I didn't loose it, didn't even loose the nail. So maybe something is going to happen, but not as bad as you saw in your dream. Or maybe you are worried about her and this dream was a manifestation of that worry... hard to say for certain.
