Often, my (realistic) dreams come true. Usually I have one then it comes true about a month to almost a year later. In August before my freshmen year began (August 2009), I had a dream one night where I met one of my best friends. In the dream, I was sitting at our lunch table and she was beside me. This... 'vision' was all blurry, but my friend's face was even blurrier. She was saying something unintelligible and then suddenly the 'vision' faded away. I met Anita, my friend in October (we started talking then) and about in January, my vision happened exactly like it did in my dream. Anita was talking and I was spacing out, looking out the window and everything was blurry, but Anita's face was more blurry (might be bad grammar, but I don't care).
On another account, on the 7th of May (about we were reviewing how to say if you're going somewhere and on what day in French and My teacher had the days of the week up on the board in french; lundi, mardi, etc...) and I turned to the board to look at it and in the background, I heard my teacher yelling at two boys acting up and I had dreamt this exact same scene 4 months ago!
Also in 2008, I had a dream about taking this History test and saw a bonus question on it about the Revolutionary War (during this dream we were on Columbus sailing the ocean blue... Lol) and near the end of the year, I had that same test and aced it. What I wanted to know was if I and truly clairvoyant or just experiencing deja vu.
