Have you ever experienced an incidence that keeps you awake at night or keeps bringing up nightmarish scenarios when ever you close your eyes to think? And it keeps playing over and over again. In your subconscious?
Firstly is to face your fears, if possible visit the location that the incident occurred,it will help you embrace the fears that lurk behind the shadows at night.
Most victims try as much as possible to forget but the nightmare won't just be wished away.
Then it is time you see a psychologist, but you can still try to improve on your sleep if you do not have the ample time to see one.
I will recommend you engage in a relationship, find love again if you are not already in one, it will help you forget.
Also take out time to go visit friends and hangout with old friends and new ones alike. This is because when you sleep at night your subconscious will try to replay things your eyes have seen for at least that week, have a memorable experience so that your anxiety will be reduced drastically.
It is also advisable to take your bath before going to bed, this will enable your body temperature to be at least within room temperature and you will feel relaxed.
Engage in sexual activity as it reduces stress and relaxes the body and also find time to exercise .
Trauma is not an easy challenge to over come, it takes self will,precession determination ,approach.
It is imperative to speak with a psychologist if it becomes a prevalent issue. Most often some drugs are prescribed.
Kind of loosely based on this is the fear of being in the woods at night. Some people who camp solo for the first few times are freaked out by the sounds they hear in the forest at night. As you hear all those sounds, your mind will generate all kinds of scenarios. You MUST return and stick it out. As you face those fears, you become accustomed to it, and those fears get smaller and smaller until they are almost nothing at all. Once awareness and knowledge is in the driver's seat, the unknown is less of a factor.
As far as trauma goes, I agree with you, though trauma can be a hard thing to overcome. Even years after the event, when it's off your mind, sometimes you will find that certain things are hardwired in from it. The way we are treated as children can create behaviors that we wish we could get rid of. We can only pray that the ones we love can understand the methods to our madness and the monsters of our past that made them necessary.
True analysis, Most victims also need to return to the scenes of the crime more than once, over time they begin to used to to feeling more relaxed and they seem to forget the ugly incident even ever happens.
