Phantosmia (Phantom Smells)

He was on the the east bank of the River Irwell,
near the confluence of the River Medlock and the River Irk,
when he first thought he smelt her.
Later that same day, and some
202-miles to the South-East, he thought he smelt her again.
Just for a second. On both occasions.
Her fragrance was built around a
modest daily spray of "Happy" by Clinique Laboratories Inc.
A light summery bouquet, it came
in a glass container
with silver lid and minimal branding.
Applied in the mornings, just before
she left the house they used to share,
by the evening its scent would had merged with her own
to form an intoxicating aroma which collected at the nape of her neck.
Just below the hairline.
Olfactory hallucination is potentially very worrisome.
It's sometimes seen as a side-effect of epilepsy,
and can also be sympomatic of an onsetting brain tumor.
Maybe I should to go and see a neurologist?
