What was this?

We've been there before,
Several years ago,
Before you closed the door,
And ended the show.

Little did I know,
That, as the curtains shut,
The lights, still aglow,
My feelings formed a rut.

There was love,
There was longing,
But the sky above
was slowly fogging.

My sight was narrow
at the Act's end
A solo arrow
I couldn't fend.

Act two began as swift
You came only to tend,
For you sealed the rift,
And, my heart did mend.

Only then could I see,
Only then did I feel,
What you did to me,
Lifting the veil.

What was this?
So familiar, yet unknown
A feeling of bliss
A warm light, that once shone

The light, from the past
Once before, I heard the tune
Maybe this time, it'll last.
An ever-glowing rune.
