Dreams can be very frightening and be a form of self-torture. They can be a passageway into your deepest fears.
I used to get a reoccuring nightmare of my mother kidnapping me, driving in a car, and driving us off of a cliff, bridge, or anything else, followed by a flash of light as I awoke (assuming it was death). I would never be able to escape. One night, though, the dream changed, as I had hit her in the head, causing us to collide into another car (yet again followed by death). Another time, I escaped the vehicle; this happened once more, along with me rescuing my mother.
Sometimes, I get these completely odd dreams that make no sense whatsoever.
I had this one dream where I was a severely obese African woman. It started out as I was walking down into a store. I went inside, bought some shoes, and next thing I know, I was at my house preparing for a date. I met up with the love of my life, and it was at a lovely restaurant. Everything seemed amazing: the music, the food, the drinks. Suddenly, my lover steps down onto one knee, slips a ring onto my finger, and says, "Will you marry me?" To this, I scream a thousand times, "Yes," as one would naturally do so. This was followed by him pulling out a gun, putting it to my head, and pulling the trigger. Then, some announcer voice said, "SO...YOU MUST BE WONDERING WHAT JUST HAPPENED!" It then began to show me a "behind the scenes" thing...which was far more sophisticated than what I believed it to be.
Some dreams, however, I find seem to become a reality.
Once, I was dreaming I was in class, and we were going over some work. I wasn't really paying attention, but I caught some key words, key surroundings, and key voices. Months later, my dream came true; I was sitting in the same desk (we switched desks every week), looking at a certain direction, I felt the same boredom, and my teacher was saying the same words.
