Hey Alien dude

my daughter saw a woman sitting at the end of her bed one night. This woman was approximately 7 feet tall. She had black shoulder length hair that appeared to be fake. She had pale skin and long thin arms and legs. This woman was waving good bye to my daughter and she floated out of the room. The woman went into the hallway and disappeared into a blue light in the ceiling.

What race of alien might this woman be?
