its just a dream...do not let it bother you unless you are into psychic and stuff...free yr mind!!!
That is scary...I have had dreams that came to be. Just make sure you have a good alarm system and locks on all windows doors etc...and a weapon of your choice...
It could mean you are having a premonition, like your mind is warning you of someone breaking into your home. It could also mean you love your family very much and you are paranoid about them getting hurt. It could mean you have been watching too many scary movies and your brain is coming up with a scenario that puts your family into a scary situation like that. (This has happened to me, it's just awful. Try watching the Unborn before going to bed. *shudder*) It could be that something similar to that has happened to you or someone you know before, or you read about something like that. Or it could just be that you have one ****** up head. Lol, just kidding. Kinda..... :P
i think a psychologist would be the best person to answer that.
