As always, I have to agree with Lynne. The "daily board" helps both the staff and the patient.
As a former patient, the "daily board" has helped me try to gain more awareness of my surroundings. When reality and mood are uncontrolled... the simple things can help you try to hang on.
I've worked in many an institution and haven't found a haunted one yet (and I'm a night owl - I like second and third shift hours where all the excitement ought to occur). But there are folks who have gone to a larger number of these than I have - the urban explorer group that posts here. They may have seen something I haven't seen yet and they have gone to many places I haven't.
Of course, as I've said before, it is possible indeed that I frighten off apparitions. :-)
In all seriousness, though, I tend to focus heavily on the people who are right in front of me. If it is the case that energy forces are out there from deceased people, I probably would be too busy focusing on the living to have time left to see the dead. They may be there and they may have their issues, but the folks I work with have some pretty serious issues in the here and now, so perhaps any deceased forces would know better than to try to distract me.
It's kind of like in a classroom when you are assessing a student's abilities. You start out with the "lesson" verbally and gauge how everyone is doing. Are people watching you, can they follow what you are saying, can they tell what day it is, can they tell what year it is, are they reading the board versus listening to you read it, are they even paying attention, if you say that it is snowing out and ask what kind of clothes you should wear, do they know to wear cold vs. warm weather clothes, etc. You learn a ton of info by asking simple questions and gauging peoples' reactions, depth of knowledge, ability to string a sentence together, stay on topic, listen to the rhythm and "prosody" of their voice, see how close they sit to others, how much eye contact they are able to make and for how long, whether they have any possible movement disorders from their medications - as I said, you check out how they are reacting and interacting, how they are processing, and how they are learning from the situation.
It's a great way to learn about people without staring at them or making them take a test. :-)
On this side of the building are several spots where there is a fenced-in space (almost like a crawl-space but with room to stand) with stalactite-like mineral deposits hanging from the ceiling. Some were several inches long, looking like little icicles.
