most psychologists agree dreams are your mind trying to put together thoughts from the day. your brain has this need to sort all of your thoughts. and all the random thoughts you have during the day, or in your subconscious, need somewhere to go. thats what dreams seem so random when theyre really not. which lets me know that the nightmares i have mean that my ex is still on my mind. plus i think there is some significance in the fact that now in my nightmares im fighting back. your mind is just trying to work through the trauma. you shouldnt try and fight them. its helping you, trust me.
