Please note that this is not an attack on Dvaita, Vishistadvaita and Achintya-Bheda-Abheda. This is information seeking question.
We know the famous analogy of the universe compared with a dream in Advaita. This claim is refused by Dvaita, Vishishtadvaita and Achintya-Bheda-Abheda .
So I was just curious whether these schools consider our dreams to be an illusion or a reality. What is their stance on dream state?
What is the dream experienced by a person after he wakes. What is the dream to him according to dualistic schools. If you can please include some references so that authenticity of the answer is established. You can answer from any one's school's point of view.
