This dream was possibly inspired by a video called How The Big Lebowski Became A Lifestyle that I saw yesterday and a part in a video where someone showed how tall Jennifer Lawrence looked at The Academy Awards (The Oscars) compared to Jodie Foster:
All that I can remember of this dream now is that I was at an indoor / outdoor convention center-like area during the day with other people, and I remember sitting and talking with the actress Jennifer Lawrence as we sat among some other people on the ledge of something that was on the ground level.
