Yes, not everyone will "at night in a dream, I am suddenly home again; by my small study window she sits at her dressing-table". Jiang Kui is like ourselves, some will forget and some will remember. Just sitting quietly or in the middle of the night, the past suddenly hits my mind, not violent, just think about it lightly, and then it's over. In such a long life, if we don't learn to forget and let go, how can we ordinary people live on?
