Does it mean anything?

So my sister told me about a dream she once had. In this dream, she said she woke up in the middle of the night and got out of bed and went down the hallway to my room. She said when she looked into my room she looked at the window, and she saw a boy looking through my window. Then she said she went back to sleep after that and woke up the next morning. I dont know if that means Peter was at my window when i was asleep, or if it was just a dream
