Another ghost?

I'm not sure if there are ghosts in my house or not. The house is nearly 100 years old, so it's possible. Plus, this happened. And this.

Last night at 3:30 in the morning Kyra came up to sleep in our room. She had a bad dream. The three of us won't fit so Jeff went to sleep in her room. Unfortunately, she was pretty awake talking about Fairyland (a story we have made up together about another world of fairies). Then, out of the blue and very calmly, she said, "Mommy, someone's here. I don't know their name. And they're going up and down."

I was pretty much awake from then until my alarm went off at 5:40. I asked her more about it this morning because I wanted to know if it was my ghost lady with the black sleeve. She told me (after many questions) it was a man with brown hair on a ladder inside the room near the window. She couldn't see his face. Is he nice or mean? He was mean. I asked her if she was scared and she said yes. But she didn't seem it last night so now I'm wondering if it was just in her imagination. Or not.
