I had this weird dream about HIMYM last night. Cristin Milioti was the main focus of the dream. At various times, I seemed to be either Barney or Marshall, and both of them separately seemed to be having a bit of a flirtation with the mother. Ted still hadn't met her yet, although he seemed to be aware of her existence, but simply that they hadn't formally met. The mother also knew who he was, and Barney even told her Ted's name at one point.
At one point, Barney was walking with the mother, but the other cast members were walking ahead in the street and then they went into a brownstone house where there was a party. However, Barney and the mother weren't invited, so they went on a date instead (don't know why he abandoned Robin). It was as if this was one last fling before Barney's wedding, even though in the actual show they were already at Farhampton (most of this dream seemed to take place back in Manhattan somewhere).
Then, as the evening progressed, both of them got into trouble in a bar fight and ended up being arrested, with the others needing to come and bail them out.
At one point, Ted even seemed to be sitting next to the mother at a bar, but they still hadn't spoken. Even in my dream, their actual meeting still seemed to be very strung out and delayed for some reason.
