Morphology
The phrase combines the concrete image 'fog' with location 'in' and 'mind' to convey obscured or unclear thinking, a metaphor that is directly inferable from the component meanings. This physical-to-mental mapping (fog = lack of clarity) is common across languages, so a B1 learner who knows the words would very likely understand the intended sense.
Etymology
Fog in someone's mind uses the picture of fog hiding a scene so you cannot see it clearly, and the mind is like that hidden scene of thoughts. So it means 'feeling confused' or 'unable to think clearly'.
