Fusing inner experience with outer environment

Siegfried Kracauer has written:

Alfred Hitchcock [...] has set a grand pattern for thrillers indulging in sleuthing. What distinguishes him from the rest of film directors is not his superior know-how but, more, his unrivalled flair for psychophysical correspondences. Nobody is so completely at home in the dim border region where inner and outer events intermingle and fuse with each other.

Write a story in which a character has a mystery to solve, told in a way that explores 'the dim border region where inner and outer events intermingle and fuse with each other.'
Some stylistic possibilities include first-person distortion of environment in the telling, non-realistic comedic farce, or allegoric fantasy with a symbolic relation between character and setting.
