There is a part of the human brain called the Fusiform Face Area. I won’t go into all of the really interesting psychology behind this, but the human brain is essentially programmed to recognize human faces in anything, even if it isn”t human. (You know, seeing “faces” in bark and clouds?) This then branches out into a general recognition of the human form. The reason you’re seeing a “ghost” there is because of the human brains “need” to find one, not because there’s an actual person there.
Apropos the ghost image on https://wastinaway.net/archives/photos/ghost.html:
