I'm going to try and prove ghosts exist! I know, riiight, but really if I were to stay in a notorious "haunted" place, and somehow managed to get evidence of a "ghost" how much evidence would I need?
I suppose it would go as follows:
-a witness
-a photograph or video of some sorts
-records that people had indeed lived there
anything else? Even if I did have photographs and video or sound recording, all of these could be disproved
