Not my memory

I was not there.
That was not my memory.
That was not my face.
This was not my place.
That was not your face.
That was not my body.
Those were not my lips.
That was not our reflection in the curtains at my place.
Those were not my colours and your scent,
Spread out on my pillows.

It must have been someone else's memory.
Someone must have told me something,
And I must have remembered it as a memory of my own.
