ŚaṅkaraAdvaita Vedānta
Interpretation
The world's apparent difference from Brahman, understood as illusion or superimposition in a technical sense that requires careful qualification: not naive non-existence, but a status 'sublated' upon true knowledge, exactly as the dream-world is sublated by the waking state. Extends to a wider claim that the entire empirical world, not only dreams, is mere illusion relative to Brahman.

From Śaṅkara’s commentary
The case is analogous to that of a dreaming man who in his dream sees manifold things, and, up to the moment of waking, is convinced that his ideas are produced by real perception without suspecting the perception to be a merely apparent one.
From Śaṅkara’s commentary
the entire expanse of things is mere illusion
has, therefore, to be understood with a distinction
