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.

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.
What impact did the great migration of African Americans in World War 1 have on American race relations? During the Great Mirgation, Africans Americans started moving North  for job opportunities since all the previous men who worked in  factories were recruited fro war through â¦ the Selective Service.People in the South were obviously racist against the African  Americans, so during the Great Migration, the right to vote caused  a lot of controversy.
