A frog in a dream often points to transformation happening in stages, much like its own journey from water to land. Frogs are also linked to cleansing, so the dream may reflect a desire to clear something out before moving into a new phase. Being in an in-between state, not quite one thing or the other, is usually exactly what the frog is naming.
It is much worse for an Artist to conceive he knows those things which he is ignorant of, than to be ignorant of those thing which he ought to know. - Cardan Girolamo (1501-1576)
