Dreaming about Abraham Lincoln, or other historical figures, signifies a form of wish fulfillment. Abraham appears because you have an abstract desire or affinity that is not fulfilled in the waking world. It often represents self-educated attempts revealing your ability to gain skills by hard work and perseverance. The things Abe accomplished were achieved through self-education; he had received almost no formal education and never attended college.
Seeing Abraham Lincoln in a dream signifies those who seek to leave oppression behind, or move forward from an unrewarding job where they are being mistreated.
Also, dreaming about Abraham Lincoln can symbolize sorrow if you dreamed yourself mourning him as he was great President who guided America through very turbulent times by ending a civil war and slavery, only to be assassinated before his time.
Dreaming of him could be an ego booster such as when he’s smiling. Abraham Lincoln was seen as a very melancholy figure, feeling rarely joy and emotional stimulation in everyday life.
