This dream possibly took place somewhere in Europe (maybe Northern Europe), and it involved at least two experiments taking place.
I was part of one experiment but I have no idea what it was about, I just remember being on a computer (maybe a laptop) inside a windowless building in a room with windows where you could see into some other rooms, and I could see the room that the second experiment was taking place.
In that room was a woman with light-color skin with yellow hair who seemed to be the person using and giving feedback on an experimental device, and a man with light-color skin wearing a white lab coat who seemed to be the scientist / researcher.
They had what looked like a mobile phone and an experimental mobile phone battery, and at some point when they took a break outside the room I talked to them about their experiment which did involve an experimental mobile phone battery.
But that is all that I can remember of this dream.
