I've been wondering recently if I could practice my guitar in my lucid dreams; one of my goals is to jam with some famous musicians, and some musicians that I personally enjoy; Jimi Hendrix, the old members of Mayhem, Electric Wizard, Paul Kossoff, Mikael Åkerfeldt...

Has anyone had any experiences like this where they've improved on a certain aspect of their playing, or played alongside someone they admire? Especially if they're a rock/metal musician! I'd love to hear it.
