That may be enough to put anyone over the edge, except for the sunshiny day.
Strange noises at night, eerie weather sometimes during the day, squalls, storms, lightning, etc.
People going in and out of the cemetery, the living remembering the life of someone who at one
time was important to him/her/space-alien not thinking they are a space alien on a planet out in the grandeur of the Universe, universes, the death topics, the has-beens, the on-goings, the well, I suppose I should stop there.
The headstones, the stones of all the deceased, the bugs, the green plants, the living and the deceased.
Okay, I am out of here.
