To write it.I've had some great ideas when I'm very awake mentally, or "in the mood". If I can somehow write my best ideas in paper, with good musical form is the problem. I'm not alone in this, even non-professional music dilettantes have this phenomenon where they can mentally conjure up amazing musical ideas spontaneously but fail to write or remember it. Even if I did remember it, writing would be hard. You have to be careful of form, harmony, possible dissonances, etc. all while maintaining your melody you imagined. This I believe comes from experience and academic study of music theory.
