I've had lots of dreams about bands and musos:
Muse - just saw them playing, no weird stuff
The Beatles - lots of strange dreams about them
The Rasmus - playing in the paddock at my old house, plus a few sexy dreams
Frank Zappa - had the most awesome sex with him
Gomez - had a sleepover with sleeping bags and popcorn, played Sega all night
Every Time I Die - I was a schoolgirl being shown off by Keith Buckley to the rest of the band
Yes - flying to London with dad and brother, seeing them at Albert Hall and meeting Chris Squire backstage
silverchair - a few dreams, mostly just meeting them and watching gigs
I'm sure there's more, but I can't remember atm
