Dream Lucid Comments

I was standing in the kitchen having a conversation with my brother when I heard and knock on the front door, I went to investigate but there was no one in sight. I walked back to the kitchen when I heard a little bang, like someone hitting a wood wall but it was coming from outside, "I'm scared" my brother said softly. I was wondering what it was when I heard it again, and again, and again, it was continuing down the wall. "I need it... I need it!" we heard a male yell as my brother started tearing up about to cry. It's hazy here so I'll write what I remember. I see him at the window - Black - We hear him yelling some more, no where in sight - Black - We hear scratching against glass in my room, he's at the window! I get worried and wait until he is gone then walk over to it. He has carved multiple different sayings into the window with KILL in big bold letters then I wake up startled in the middle of the night.
