Hey gokulramdas, I am understanding that your definition would be to take the nondual state consciously into dreams and deep sleep? If that is correct then I would be an amateur meditator. I know there have been some studies done on meditators in their deep sleep and have read that tests done did show they were consciously aware....If that's true then to my way of thinking there should be whole universities set up to study such phenomenon on a full-time​ basis.....
