Loss of senses!!!

Sophia wakes up from her a long sleep. She found herself in her bed but something was weird. She was in her home, her actual home, she was where she was brought up as a child, when she lived with her parents, the place she despised coming back as she was often alone there but standing there at that point made her emotional. She was king of happy to look at her old house and it was in very good condition. It looked like someone took really good care of the place when she was away. Without her parents, family and friends, Sophia never had courage to visit her house again. Many memories, good memories came rushing back to her. She was happy in a long time. She looked around to see the pictures hanging on the wall as she saw them last time. She heard some voices coming from downstairs… from kitchen. She went there to find someone cooking there. But who was it?
