music dream

I often dream of music. Not just any music - music I've never heard before, but if I could write music would probably be very rich after waking up and writing it. I never thought anything of it until my husband told me he had never heard of anyone hearing/ creating music in their dreams and he thought it was a "special gift". Is he right? Is this unusual? I always just woke up wishing I could read/write music so that I could keep the melodies/harmonies because the music was always so awesome. Ranged from world/ alternative to classical and notes or arrangements I'd never heard...
