Dreams

Dreams are recollections of memory which all candidates chosen for a chance of resurrection receive from the night of Day 1 through Day 6. They are flashbacks from a certain event in their lives, and are vital hints for the candidates to know more about themselves and the life they used to live before they died.

Hilde
Not much is known about Hilde's dreams, but it was revealed in Day 5 that she dreamed of a friend who was hurt by "bad people". This connects to Kirell's own dreams about a friend who listens to her problems, hinting that Hilde and Kirell have shared a friendship in their past lives. This is further proven by the dreams Kirell receive from the second play through and onward, where the silhouetted characters were all revealed, showing Kirell's friend was indeed Hilde.

Through certain paths in Day 5, Hilde's decisions will be heavily spurred on by her dreams. If Kirell has a low likability with Hilde, Hilde will question Kirell about her plans. Hilde will then ask if there is a friend Kirell wishes to go back to after she gets resurrected. If the right answers were selected and Hilde's likability was tolerable, Hilde will believe that Kirell was her friend when they lived.

If the selected answers were against Hilde's beliefs, or Kirell has critical likability, Hilde will deny all of Kirell's claims and attack her, stating that "bad people" like Kirell hurted her friend (whom she does not believe is Kirell but is, ironically, her).
