I believe the general idea is that if you see things that are not human this is regarded as an indication of potential psychopathy... with the idea that this is a projective test, which is supposed to therefore mirror the person projecting... if people only see shapes, islands etc... very bad.... insects are less 'good' to see than mammals and so on... so 'flowers' might be worse than darth vader because they are inanimate etc
The original interpretation has to be evaluated within its own cultural context of course. An adherant of an animist religion might be quite used to viewing and 'communicating' with plant, insectoid and animal 'entities', with the aid of trance, meditation or psychedelic sacrements, and thus for them seeing such entities might be fairly normal and healthy. Indeed, in such a society, being only able to relate to humans might be seen as a blinkered form of mental illness.
Oh, that's good to know, I was thinking that it is bad to see Cthulhu and Vader everywhere!
Of course, I would say that as I saw birds, monkey demons and beetles in the examples above... lol
