Yeah it means all is one and that one Consciousness is you.Thoughts as well all preceptory experience are just transitory experience.You are nothingness that holds.
You never moved you are dreaming from Here for eternity.There is no nonduality it's just like anything else imagination of your mind same as everything else.
Your Mind is imagining your body and the world.You are experiencing your mind's imagination from within imagination.
Reality isn't physical it's mental.
You are all alone . You are God dreaming.
