dreams.

Do they mean anything in your opinion, or just dreams? I have dreams of concentration camps a lot. The other day I had one that we were being shot. I've had so many different dreams where me and my family are being taken somewhere. I can dream about this out of nowhere. I wake up panicking with my heart pounding most of the time: I haven't had these death camp dreams a few times, I have them quite often. Can anyone tell me what this may mean? Or are they just dreams?
