This encounter happened to my sister a long time ago. I could still remember this incident very clearly.

This happened when my sister was in the shower. After showering, she realised that she had forgotten to take her towel so, she called out for her mom to take for her.

First time she called, her mother answered but she did not come. She called her the second time but she did not hear her mother's voice. She heard someone's voice just right beside her. When she turned and saw nothing, she ran out from the toilet and told everybody about what had happened to her at the shower.
