Yeah I had a couple very unsettling ones this past week too, including a bizarre one in which I was using LSD and drinking... All sorts of weird things happened and I blacked out in the dream. It was really awful and left me shaken for a while after I woke.
But I've come to realize that these are not that unlike any other nightmare. There may sometimes be a correlation to stress in my day to day life or my balance being a bit off, so I try to look at that and make changes if warranted.
Sometimes though, dreams are just dreams. Our nocturnal minds sorting through memories and firing off imaginings and gazing into the mysterious depths of our consciousness.
Dreams in general are mysterious. Try not to get too flapped about it.
