Emotional memories are etched particularly deeply.
The hippocampus, the center for forming memories, and the amygdala, which processes emotions, are closely connected, so the more intense an emotional experience is, the more deeply it becomes engraved in the unconscious.
Thus, even if an event happened long ago, when a similar situation arises, the emotions that had been dormant in the unconscious rise again like a wave, bringing those feelings vividly back to life.
This is because emotion has the power to firmly hold on to memory.
