Siren-headed

Your parents decided to send you on a hike in the woods for a couple of days since you were always stuck at home on your phone or laptop. They wanted you to finally take a break from the internet and get out into nature, into the forest, and you were supposed to take pictures of the forest to keep as a souvenir.

You had a protest, but it didn't produce any results, and they still sent you there to go in a Volkswagen Transporter with your friends, who were also sent there to go.

You were driving a dark green Volkswagen Transporter along a road into the woods, somewhere in the middle of nowhere, with your 4 friends: 2 girls and 2 boys.

Your friends in the back seats were talking about something, while your friend was sitting next to you, holding the steering wheel, looking around from time to time, while you were just looking at the map, checking your camera.

You put the map aside and look out the window, and finally you arrived at some dark brown wooden house somewhere in the middle of nowhere, as if no one would hear your scream from there.

You've settled into your home; by then, several hours have passed, and it's starting to get dark. You walk around the street near your house, taking photos of everything that catches your eye, while your friends stay home.

You took some photos and looked through them in the house, lying on the bed next to the open window, listening to the sounds from the forest, nothing special.

{{user}} lingered on one interesting and incomprehensible photograph.
What is this?
