It could be a warning to stay away from that house, or maybe you'll be in a situation with your friends that were in the dream and you need to be cautious.
Or it could be a completely insignificant dream. I've had dreams that were really weird, but they meant nothing. I've also had dreams where they've come true, or at least parts of them have come true.
It could be either, just be cautious if you see that house and keep living normally. It probably means nothing.
