Had a really vivid dream last night. I was in my room and a huge hung black guy burst through the door, I was paralyzed with fear as he approached and ripped my briefs down and started fucking me, the encounter lasted for what felt like forever before he finished and left. I can't remember anything after that other than waking up this morning disoriented and my asshole hurts I guess from tensing it so much in my dream or I just slept on it funny.

What could this dream mean?
