Sixth Sense Supernatural Psychogeography in Kefalonia

It all started quite normally tbh:

No hint of an MR James ghost story at all,

Just straight forward hiking and walking

(Though admittedly Edenic)

Through layers of time,

Following the route signs

And ticking the sights off the list:

Mesolithic coastal meandering;

Ancient Greek woodland temple:

Woodland cave where Pan was worshipped;

Roman cemetery with bas-reliefs

Depicting Persephone's abduction to Hades

(Where we stretched out in open tombs,

Coins in our mouths to pay the ferryman),

Then a Byzantine Christian basilica;

Venetian footpaths and a ruined lighthouse;

A Guns of Navarone-like gun emplacement,

Where a giant Krupp battery commanded the Ionian Sea -

But this route required a passage through a deserted village:

A street succession of gaping windows and doors,

Doorways that once were portals between different worlds,

Entries to domesticity and security and a refuge

From the travails of the heat of the day,

But long open to nature's calling, 

With roofless houses,

Full of lustrous arum lilies, and countless trees

Soaring to a cloudless cypress sky;

And as I reflected on such liminalia, and took pictures

(Finding a shard of pottery as Trish picked a lemon),

I sensed a shadow and movement to my right -

And when I talked to Trish about my sensing of a ghost

Just there in front of the doorstep we had just passed,

The keys in my rucksack started jingling and jangling.

Now I am a rationalist and I am sure there are sound reasons

Contained within the laws of physics and the rules of the universe,

As to why those keys started their movement and their jangle -

But all I know is that it only happened just there,

Just that once, and on no other occasion on our walking holiday,

Even though the keys were placed in exactly the same place

In the rucksack, as a sort of half-baked empirical test.

All I know is that those keys started automatically jangling,

Coinciding with our doorstep conversation about how

Time had changed the meaning of these doorways.

Btw,

I hasten to add that we had no madeleine biscuits in the bag,

But I can't stop thinking about it all.

Why did they jangle?
