Shadows can be explained. But a ghost that litters I cannot
Though maybe homeless/potential squatters.
My wife has all sorts of stories of lost socks or why the remote ended up where it did. But...she also forgets what she did half the time.
Idk I just think most things can be explained and if not, I'm still not sure about the ghost explanation. Might as well call it invisible alien beings or anything else and it would be just as plausible or unproven.
The idea of ghosts is interesting, such an old timey concept based on an old/pre-science concept of a "spirit" because before science people thought there must be something inside of our bodies that "enlivened" us or made our bodies "spirited". Ie why our bodies moved while alive. Also to explain why our bodies suddenly stopped moving at death...they figured something must have left our bodies. Of course now we know that's all mumbo jumbo and our brain, or cessation of brain activity, is the cause of all of it and the end of it. Similar to how humans thought some entity must have caused apples to be "thrown at the ground" from trees, when it was gravity all along. So idk as to what "vehicle" could explain a ghost. Very old idea with zero point zero reason behind it. But because it crossed over so many generations, the idea still exists, even though the idea behind it, the vehicle/post-bodily spirit like entity, has been proven not what it was thought and has zero basis.
