kronick Reviewed by kronick on . Reoccuring stuff? This one time when very stoned I watched IRobot with some friends. During the moive I kept saying "I saw this movie before." Which I felt like I had seen it before and I was actually saying (small things) that were happening next in the movie. My friends kept saying that i'm crazy and too stoned. We were talking before the weed and they knew I had wanted to see the movie for some stupid reason. I kept saying this throughout most of movie because I was tripping to some crazy shit.
