Last night I had a dream I was with my girlfriend in a house I never seen right, and someone knocked on the door but I could see him looking under the door. So I asked who it was and he just threw a pencil inside. I asked again and he didnt answer, so I opened the door and he pulled out a gun and came in and took something. He came back in and I grabbed a knife because I was furious, but then i woke up.. With a boner. What does it mean??
