Thanks for the reply Michael.
An odd thing happened the other night - was wondering if it happens to anyone else?
I was photoreading a book before I went to sleep - during the photoreading step I was listening to some relaxing music - partially to occupy my concious mind and to relax me. I intended to let the material I had photoread incubate overnight. I dreamt of the book I had PR'ed that night (I gather this happens a lot) AND the music I was listening to - the music was so vividly dreamt that I woke up confused since my stereo was switched off! 
Cheers,
James
