Passage of time

Souls emerging from the tunnel of time. Passing through the physical world.

Our physical world weathers, grows and decays, is destroyed and recreated in it’s own time.
We only pass through changing a little as we go.

My intention when making this image was to talk about how people have lived for many many generations in some cities. Through war and natural disaster, through political and technical changes. But things are rebuilt and another generation occupies that space.

However the image seems to contain much more.
What is behind the doors?…… Death?….. A exit from the physical world.
Is that a minus and plus sign above them?
Who is watching over the passage?
What power do the cables carry?
