The Spooky Night

It was late in the night, Rhea walked back to her home under her umbrella on the rainy night of Cherrapunji. She reached home and put her umbrella on the umbrella stand, which was now drowned in water. She climbed up the stairs of her house, said good night to her cat, and got up on her bed. Just as she slept, the doorbell started to ring vigorously. She got frightened. She slowly walked down the stairs, towards the door. Her body was now shivering, from head to toe. 

Just when she put her hand over the doorknob, she heard a spooky voice that said, "Open the door Rhea, open the door!" It was followed by evil laughter. She froze. She could feel her heart racing as she took a gulp. She told herself it was going to be ok and it is nothing to worry about; ghosts can't be real. She took a deep breath and opened the door slowly. At exactly that time, struck lightning nearby and she saw a tall shadow with long curly hair, long sharp nails, thin body and she looked just like a witch. Rhea started to panic as the witch came closer and caught hold of her. 

She squished her till Rhea was out of breath. As the witch moved closer to light, Rhea got a glimpse of her. It was none other than her dear sister, Anvi! She removed the grip of her hands from Rhea and said, "Happy Birthday Rhea! I can't imagine we have grown so old!" Rhea gave her a grin.

So that solves the mystery.

Anvi had gotten a cake for Rhea, so they took it to the dining hall to cut it. Rhea was about to smash the knife on the cake when someone at the door started to knock and ring the bell fiercely. 

They opened the door in exuberance believing it would again be someone who had come to surprise her on that special day. This time, it wasn't her friends, it wasn't her relatives, it was someone she hadn't known, someone 'witchy'. "AAAAAAAA" They shouted. 

So who was it?
