Huh?

This happened when I was still connected with my previous employer...

I went to the comfort room and I saw a woman combing her long straight hair. Nobody was there except her and me. I noticed that while combing, she's also smiling at herself in the mirror. I thought she would stop smiling since I was already there but she remained smiling. I got scared at her and I immediately packed up my stuffs and went out of the CR. Until now, I've been thinking... Is she just weird or she's the lady ghost in the 27th floor? Hmm...
