Not sure I agree there, Witz. It's a sign of unresolved past trauma which needs to be dealt with in a psychotherapeutic context.
I would recommend 'The Power of Focusing' as a good start.
There's no point having past memories floating about if you're trying to stay in the Present - they drag you here and there. They need to be dealt with on their own terms.
Everyone has to go through this; it's nothing special or unusual.
