> when on the verge of sleep my sound imagination can switch on and I hear music as if I were at a concert hall - dramatically different from my day-to-day experience. I used to be like that in the past. I would sit in a chair and the music would come. Then I knew I was close to sleeping, and it happened every night when going to bed. When I woke up the final stage of sleeping also had music, then it was suddenly, brutally switched off and I was awake. It felt as real as if it was heard live. The thing is, the music was always something I'd never heard before, and it was huge and with lots of instruments. Classical, mostly. It was very similar to the "music everywhere" experience in the Salaxian ship described in the novel "Dirk Gently's Holistic Detective Agency". For various reasons I went through a sleep-deprived phase, and after that time I lost the music. No music when going to sleep, and none when waking up. After many years I started to get a different experience, I would dream about music events (watching some band, for example, or some other event), hear nice (non-classical) music, and, if I woke up, trying to find a pen and write down the chords or the music - but it fades so quickly that after writing down the beginning it would all be gone. The brain is the strangest thing.
