Dream of

I had this dream this morning. Lisa was in it but I've forgotten why. The first part of the dream I'm at the McDonald's near Stuy with 5 dollars trying to decide what to get, and trying to decide between ice cream and cookies (I was really hungry in my dream). On the cashier's counter are 5 plushies, the 5 nearest to me on my bed, and one of them was the pillow pet Ivy gave me. Then the door opened, and this huge flood came in and swept us all out of the store and then back in the store, apparently trying to clean it. Then the dream transitions, and I'm neck deep in water, supposedly in a dress, and David, in a tux, is pulling me along to find Karen, who is standing in a line of people, also in a tux. David asks me for help with some physics, but I suck at physics, so regrettably I can't help him. Karen makes some sort of weird comment to me but I've completely forgotten it.
