From the perspective of Turiya and to set the stage:

https://en.wikipedia.org/wiki/Turiya#Advaita_Vedanta

"Advaita posits three states of consciousness, namely waking (jagrat), dreaming (svapna), deep sleep (suṣupti), which are empirically experienced by human beings, and correspond to the Three Bodies Doctrine:

1. The first state is the waking state, in which we are aware of our daily world. This is the gross body.

2. The second state is the dreaming mind. This is the subtle body.

3. The third state is the state of deep sleep. This is the causal body.

Advaita also posits the fourth state of Turiya, which some describe as pure consciousness, the background that underlies and transcends these three common states of consciousness. Turiya is the state of liberation, where according to the Advaita school, one experiences the infinite (ananta) and non-different (advaita/abheda), that is free from the dualistic experience, the state in which ajativada, non-origination, is apprehended. According to Candradhara Sarma, Turiya state is where the foundational Self is realized, it is measureless, neither cause nor effect, all pervading, without suffering, blissful, changeless, self-luminous, real, immanent in all things and transcendent. Those who have experienced the Turiya stage of self-consciousness have reached the pure awareness of their own non-dual Self as one with everyone and everything, for them the knowledge, the knower, the known becomes one, they are the Jivanmukta."
