As-salaamu `alaykum
What a horrible event. May Allaah forgive you. Inshaa' Allaah the images will go, maybe you could say the du`aa before you sleep, "Allaahumma innee as'aluka ru'yan saalihatan. Saadiqatan ghayra kaadhibatan. Naafi`atan ghara Daaratan." O Allaah, I ask you to grant me a good dream; truthful and not false, beneficial and not harmful.
Allaah knows best, perhaps just a good dream could help this go away, and should at least protect you from bad dreams about the event.
Was-salaam
