Reveal an alternate world only in the reflection

Edit my uploaded full-body or environmental portrait so the real scene remains grounded and photographic, but the reflection in [REFLECTIVE SURFACE] reveals an alternate version of the same place and person.

Above the reflection: preserve the subject's exact identity, clothing, pose, environment and natural [REAL-WORLD CONDITIONS].
Inside the reflection only: show [ALTERNATE WORLD], with the same person wearing [ALTERNATE WARDROBE OR ROLE] and matching the exact mirrored pose.
Physics: reflection geometry must obey the surface angle and camera position; ripples, dirt, edge distortion and reduced contrast should affect the alternate image naturally. The subject's feet or contact point align perfectly with the reflection.
Lighting: real-world light remains unchanged; alternate colour may glow only within the reflected surface and cast at most a very subtle local spill.

Do not turn the reflective surface into a portal hole, change the real person, duplicate bodies outside the reflection, ignore mirror reversal or add fantasy elements elsewhere. No text, watermark or impossible anatomy.
