Yin and Yang:
 
Heavy Yin influence
The situation
Even before entering a house, you can sometimes sense darkness - both physical and atmospheric - attributable to dense foliage, overgrown hedges or too close a proximity to woodland.
The effects
This has the effect of stifling the light of Yang and will create an unnecessary heaviness.
The solution
It will help to cut back the foliage that is the cause of the problem so that it has less of a negative effect Up to a point, the more windows there are in the house the better. If the house is dark, introduce additional windows. If this is not possible, maximise the light available by having light curtains and hanging them beyond the edge of the window area when they are open.
