For example, panic attacks, particularly those that occur at nighttime, may result in lightheadedness, which can in turn cause dizziness and hyperventilation. Patients with post-traumatic stress disorder may also feel dizzy when lying down, although this is rare.
Introduction. The Great Migration, or the relocation of more than 6 million African Americans from the rural South to the cities of the North, Midwest and West from 1916 to 1970, had a huge impact on urban life in the United States.he Great Migration also began a new era of increasing political activism among African Americans, who after being disenfranchised in the South found a new place for themselves in public life in the cities of the North and West.
Arguably the most profound effect of World War I on African Americans was the acceleration of the multi-decade mass movement of black, southern rural farm laborers northward and westward in search of higher wages in industrial jobs and better social and political opportunities.
