The Dreamer

I; the autumn
I; the evening star [#]
I have been an echo

I shall be a wave
I shall be the moon
I have been everything, I am myself

I; the summer
I; the ebony
I am the dreamer

Vespero: the planet Venus as a star of the late afternoon or early evening [Lat. vesperus, evening, evening star.]

So, most of it, you got right.
