Seeing Ghost?

I was at work last night and we were talking about the rooms we slept during our break. I can't believe what my Canadian colleague said. According to her she is seeing ghost or as what she said she felt the ghost near her when she went to her break.  She said that it was her patient who died the other night. I am not so sure about this. Maybe she was just dreaming. Anyway, enough of this because I don't believe it unless I see one. Maybe not because I am scared too. LOL. I need to go to bed now because I am still working tonight or else I will develop acne and need to spend fortune with natural acne treatment. Goodnight peeps!
