I was just walking, carefully looking at all the artefacts in the museum. That’s when I noticed it, something strange was happening. I turned to look beside me. 2 people were there dressed in very brown/grey clothes. It was odd. 2 minutes later I saw them again this time looking at a wall. I realised that everyone was taking photos of the wall and I was the only one that saw the 2 other people. I took a photo and looked up at the wall. There was no one there. I looked back at the photo, it was of 2 people walking through the wall.
