you can get rid of flashbacks. I have gone through many flashback cycles since 1986. A flashback is a piece of memory that is upsetting to the person. The way to get rid of a specicif flashback is by desesitization-

For example a person experiences a rape. After the rape the person has flashbacks - they see pictures in their mind of what they saw during the event. They hear sounds of what they heard during the event, they smell the same smell of the event, they taste the taste of the event. This happens when a person encounters sopmething in their day to day life that reminds them of the attack - for example going grocery shopping and seeing someone that looks like thier rapist. can trigger any one of those types of flashbacks.

To get rid of them the person needs to write, draw, and talk about it so much that it no longer bothers them to say what happened, to draw what happened. when the personis no longer feeling emotionally traumatized by it and knows everything that happened during the event the flashback for that situation goes away.

Depending on how many traumatizing situations a person experienced depends on how many flashback cycles a person goes through.

I call them cycles because with each new memory that tries to come to the surface I go through the same type of flashbacks- noises, pictures, tastes, smells, and a variety of fellings and body sensory ones.
