NIGHTMARE: A Vision

I have seen a lot of dreams. Some are exciting where some are horrendous. Most of us have a lot of nightmares. But just think how terrifying it would be if it became true. I am telling you this because I have been through this. I even remember the nightmare I had like 7 years ago. I don't know how but I randomly get dreams I never thought of. I usually dream about ghosts and all but this time it was different and kind of a "vision" as most of it became true. This dream was about a lady wearing a weird dark textured scarf having something written on them. It was a blur and congested but there was something written on it. She was following me and I can see her. But whenever I turned back she vanished. It felt like she was around me but invisible to my eyes. I can see her reflection in the mirror but can't see her in reality. I started sweating, frightened as I didn't know what was happening. Suddenly, there was a glitch in the lights and when it became normal; everyone had disappeared. I was freaking out and I don't how but something touched from my shoulder and I woke up. Just a week after I saw that dream, a lady was a victim of that vision. Whatever I saw in my dream, mostly everything happened with her and she went to a comma.
