Hola Laurinha y a todos,
In my opinion I would reserve the use of ‘awake fall’ in this context for poetry, song lyrics or literature only and would in that case suggest ‘awake the fall’ or ‘fall awakens’. However, to be honest, one generally associates spring with awakening and fall with hibernation (sleep) and perhaps is should be that one “awakens from the fall”.
Of course, in UK you would say autumn rather than fall anyway, which loses the poetic playfulness.
A ver que opinan los demas.
Great way to think about the words though; you must be a poet yourself.
