I have rarely had muse related dreams...
The first one I had was a few days after I saw them at Parc des Princes in June 2007: they had a gig in a stadium. I was sitting waiting for the gig to start, when Matt came and took me by the hand to a building where there were Warner employees. For some reason I was very nervous because I didn't know why I was there nor what I was supposed to do. Then, suddenly, I found myself in a street close to the stadium where they gave their gig, and Muse were standing behind me. I turn and see Matt coming to me. He gave me a kiss on the neck . And my alarm clock woke me up, so I don't know how this dream was supposed to end... Weird
In another one, I was the blonde girl in the Knights of Cydonia video (I wish I was as fit as her though)
