Sakura and Her Mother's Memory - S1.E6

Naoko tells everyone a scary story about a bright light she chased into the woods. After school, Sakura and her friends visit the woods to see the light Naoko saw. When they do see it, everyone runs in fear, claiming they saw something appearing from the light, but everyone saw something different. Sakura returns at night in case it was a card despite her fear of ghosts. After following it near a cliff, the light takes the form of Sakura's deceased mother, Nadeshiko. Sakura, who is delighted to see her mother, walks towards it and off the cliff, but she is saved by an unknown entity and safely lowered into Yukito arms who is passing by. Sakura returns to the cliff a few days later and once again walks off the cliff. She realizes that it couldn't be her mother and discovers it to be really The Illusion.
