To understand what you see you have to remember Snell's Law - the angle of incidence = the angle of reflection. So what you see is the lamp and pictures on the walls to the right of the photo.
If that's too difficult, let's look at a framed picture acting as a mirror on my office wall..
|Map of the County of Lincolnshire|
The reflection comes from the window off scene right. I hope you can make out the branches of some trees.
In the bathroom a shaving/beauty mirror stands on the window ledge and gives this effect.
What interests me about this shot is not the image shown in the mirror, but the frosted glass window behind it. It is not green, The lawn outside is what makes the background colour.
When I saw the result of my next shot I though immediately of Alice and Through the Looking Glass.

I eventually got sent out in the rain - I took my camera with me.

And when I saw this I thought of Gene Kelly.
So I guess that we need to do now is to dance off to Carmi's for some more mirror images.
