I recently been having nightmares (not the first but a little more often then usual). One of them was a week before Halloween. I didn't watch any scary movies or read anything scary but I dreamed about a woman in black with long black hair covering her face and floating above me. She was screaming in my face. I tried so hard to wake up and scream but couldn't. It took awhile to finally wake up and when I did I remember in my mind I was calling out to one of my brother.

Can anyone explain to me what the dream meant? Am I having nightmares because something might be bothering me even though I do not have a clue if there is. Thanks
