depressions
Hollows or doldrums
Depressions are low areas or sunken places—in terrain, in mood, or in economic activity.
A depression in the ground is a hollow or indentation.
Psychological depression is a state of persistent low mood and diminished interest.
Economic depressions are prolonged downturns more severe than recessions: the Great Depression of the 1930s.
The word connects these through the sense of being pressed down below normal levels.
