visit from a entity?

A young girl was sleeping peacefully, then she heard a knocked on the window. She thought she was still sleeping so she ignored it. She heard the knocked again so she got off of bed and slowly moved the curtains aside, there was nothing. She was about to close the curtain when she saw something on the corner of her eye. She saw a human figure standing right outside her window and the figure was looking right at her. The figure got closer, it was a young man, with long black shoulder length hair and a very pale complexion and dark red eyes. Next to the man was a white cat with glowing black eyes.She close her eyes and count...5...4...3...2...1...0, when she open her eyes the man was gone, but the cat was still there and visits her every night.
