I remember one dream.

All I remember (maybe it was just that) is Justin Timberlake was performing while dancing and singing and moving around so not staying in a stage, he came face to face with Britney Spears and they both were shocked but Britney smiled and I think said hi and he continued after smiling or and doing a gesture or and saying something to her. She was dancing and sometimes the camera showed her and he went back to her to dance with her. Water was all around or at least where she was.
