Other info: I never had a dream like this and never since then. I've always had constant dreams but none of this context.
house window dream
In my dream, I was in a house. I was wearing some type of gown and it was dark. I was looking around and noticed a window. I walked to it and looked out. I saw trees and wind blowing leaves. It looked nice and seemed to be in a neighborhood. I looked up to a house across the street and looked to the second story window. I saw what looked like an older woman, being strangled by a man. I screamed and ran to get a phone or something, but when I turned I ran into the man that was strangling the woman and then I woke up.
