In which I am a fish

And there is water
around on all sides,
like The Great Flood.
And I am a fish,
complete with gills.
You, too are there,
its just the two of us
in the flood.
Two fishes,
circling,
round and round,
afraid they'll be lost.
In my most favorite dream,
I become a fish,
I have gills
and you retain your hair
and you ask me,
"Is there nobody?"
"No, just us and clear blue water and the Sun above."
"Is it eternal?"
"I don't know".
