Writeacher, I've found an example of interior monologue with two levels of narration. Now I have to link it to my definition. Can you please help me?

The second type of interior monologue is characterized by two levels of narration: one external to the character’s mind and one internal.
Example
"Leopold Bloom ate with relish the inner organs of beasts and fowls. (objective, external level of narration, use of third-person narrator)

He liked thick giblet soup, nutty gizzards, a stuffed roast heart, liver slices fried with crustcrumbs fried hencod's roes. Most of all he liked grilled mutton kidneys which gave to his palate a fine tang of faintly scented urine.
Kidneys were in his mind as he moved about the kitchen softly, righting her breakfast things on the humpy tray. Gelid light and air were in the kitchen but out of doors gentle summer morning everywhere. Made him feel a bit peckish.
The coals were reddening.

Another slice of bread and butter: three four: right. (second level of narration which takes place withing the character's consciousness)

So the external is the narrator telling us what the character thinks and feels?

Interior is the character's own thoughts?
