I always dream if/when I have a problem, it's very rare when there isn't music in them. I love cheese which we seem to get a lot of here, so I always have weird dreams. Various favourites have turned up to give advice. I've sleep apnoea so when I have a bad dream I know there's something not right w/ my CPAP.
I was (still am) a massive fan of Gary Moore; I saw him live twice. I quite fancied him too (!) I loved his blues so much I sometimes thought in blues lyrics. One night I couldn't sleep cos my chest hurt so much I was struggling to breathe, which I thought was normal due to my apnoea. Next morning I found out GM had died that night.
I dreamed of a man in a black hat for ages, in a fantasy garden, tapping his staff on the ground. I just thought it was due to me reading so much high fantasy. A few months later I discovered the joy of Discworld, & now spend ½ my time on the Disc.
