The dream I had last night also featured my guitar!
At the start of the dream me and my family were on a coach, and Mika was sitting in the seat in front of mine and my sister's. We spoke to him a bit, but both me and Mika were quite shy.
Then the coach stopped by a lake, and everyone started to get out. But before everyone was out, the coach started to slip into the lake. Mika, my parents and my sister all swam out to safety but I was a bit stuck so my mum and Mika came back to save me! Then I realized my new guitar was still in the coach and I was going to back down into the lake to get it but Mika held me back (which was quite cool! ).
