As a Brit and mentor, but not a teacher, my interpretation is as follows:
psyche - definition of psyche by the Free Online Dictionary, Thesaurus and Encyclopedia.
1. The spirit or soul.
2. Psychiatry The mind functioning as the center of thought, emotion, and behavior and consciously or unconsciously adjusting or mediating the body's responses to the social and physical environment.
Pollyannish - encyclopedia article about Pollyannish.
The Pollyanna principle or Pollyannaism describes the tendency for people to agree with positive statements describing them. It is sometimes called positivity bias.
The concept as described by Matlin and Stang in 1978 used the archetype of Pollyanna, a young girl with infectious optimism.
3-a ceiling fan/light combination
Exactly what it says, it is an inexpensive, suspended, long-bladed, non-enclosed, ceiling fan that includes a lamp or lamps. It normally has a means of adjusting the fan speed to regulate the degree of cooling. It's used to provide a gentle degree of cooling without resorting to high power consumption air conditioners. Particularly useful in open air restaurants.
4- "rose-colored glasses" syndrome
I've regularly come across it as "rose-tinted spectacles", which means looking at the world from a very optimistic viewpoint.
5- a spirit of genuine belief
I've regularly come across this in the negative, as: "a spirit of genuine disbelief" i.e. the person concerned just could not believe what their eyes were seeing - it was so far remote from the norm.
6- overwhelmed = overcome, as in "overwhelmed with grief"
7-brought on by = caused by
Hope this helps
