What things does Hester think about it while she is on the scaffold?

Hester thinks about things that have happened in the past. From the text:

"Reminiscences, the most trifling and immaterial, passages of infancy and school-days, sports, childish quarrels, and the little domestic traits of her maiden years, came swarming back upon her, intermingled with recollections of whatever was gravest in her subsequent life; one picture precisely as vivid as another; as if all were of similar importance, or all alike a play. Possibly, it was an instinctive device of her spirit to relieve itself, by the exhibition of these phantasmagoric forms, from the cruel weight and hardness of the reality."
