Was it a dream?

It wasn't a bed I was sleeping on
It was something flowing and colder
It was something having waves
I was floating instead of sleeping
with my face facing the sky
and the flowing water being my bed
with all my hair open and wet
with my gown rustling with air
my eyes were peacefully shut
yet the dreams were flowing through them
And somebody was watching keenly from a distance
It wasn't a dream, was it?
Or I was floating somewhere between 
wakefulness and dreaming?
