Tru here.

SunLight is very important to me.
i designed this house for maximum benefit of daylight.
All exterior walls have loads of windows, and doors are clear glass, along with a glass-enclosed wrap-around porch,
… but, until dementia symptoms arrived, at night i needed it very dark.

Before dementia symptoms i needed it very dark at night, but
now, because of nocturnal hallucinations,
i NEED to orient soon as possible when waking up.

Sometimes the hallucination-environment is super-imposed over my bedroom environment,
so need a bit of light to orient
— but not too intense that i cannot return to sleep.
(Interferes with melatonin secretion.)

Hope is to return to sleep — but not return to the ultra-vivid scary environment of my dreams.
With dim lighting i can recognize familiar shapes and items in bedroom or living room,
so it reduces likelihood of these things being incorporated into dreams
during this nether-time between sleep and wakefulness.

Minimum of 2 side lamps (wall sconces) on each wall, in each room of the house.
Each of these Lamps hold a 7-watt bulb, or are higher wattage but gold/orange in color.
Having multiple low-wattage lamps helps eliminate shadows that can be mis-interpreted as part of an illusion.

“Even dim light can interfere with a person’s circadian rhythm and melatonin secretion.
A mere eight lux—a level of brightness exceeded by most table lamps and about twice that of a night light—has an effect,
notes Stephen Lockley, a Harvard sleep researcher. ” (per Harvard Health Publishing * — see article in Links below).

On 15 Sep 2014, Victoria L. Dunckley M.D., of Psychology Today, wrote:
“The healthiest light is sunlight or candlelight, followed by incandescent, then halogen, then LEDs, then CFLs.
I recommend that parents of children with psychiatric, neurological, learning, or chronic medical conditions
switch out all CFLs in the home for incandescent or halogen bulbs.”  (CFL is Compact Fluorescent Light * see article in Links below).

.

When evening arrives, the side lamps go on throughout the house.
Overhead lighting is turned off an hour or two before bed, to encourage a feeling of sleepiness.

((Another change is that i am No longer able to use flashlight; creates dis-orientation for balance, and i will fall. See Link at base of entry.))

PS: it is difficult to understand how very long it takes me to write these days. began this entry 18Jun2018, and worked on it again 07Sep2018.  Spent 4 more hours on it 09Jan2019, then made some revisions, and created a graphic, but still cannot understand what i am reading well enough to know if it makes sense, so husband helped me finalize it on 12Jan2020.
