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.
Between 300,000 and 1,000,000 African-Americans moved north during this perio â¦ d, largely in response to an increased number of unskilled factory job openings as northern manufacturers boosted production for World War I. Black migration between 1916 and the 1960s remained strong, except during the Great Depression.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. This is because when the African Americans  moved to the Norht they were given the right to vote.
