Strange Reflection

Hi there!
I'm glad I finally got to make this post!

About a week ago, I travelled to Lagos, Nigeria from Ondo state via road transport.

I discovered a strange reflection while in the vehicle and I took pictures to share with the community but somehow, I've been caught up in other activities but here it is finally!

There weren't many passengers on that day so the bus was a bit scanty. I sat down alone at the back of the vehicle and tried several times to find a comfortable position to sleep but to no avail. So, I resorted to turning to face the glass of the vehicle behind me to look at the vehicles coming from behind. It was an interesting view and while I was enjoying the view, I noticed a strange reflection on the glass.

It was a reflection of images of people and the sky. I was confused at first but I eventually figured out that it was the images of people sitted inside the vehicle as well as images from outside the vehicle.

From both sides of the glass, the were reflected on the glass. The resultant reflection is as shown below;
