i was told in therapy years ago to try and imagine putting each bad experience in a box of its own, seal it and stick a lable on it then stack it in a corner, it worked great as a way if dealing with one problem at a time, i only opened a box when i was alone or with my therapist and had time to deal with it. fantastic system. i was able to rationalise many problems and bad experiences that way.
It was not done as a way of dissociating, it was done simply as a way of ordering and prioritising thoughts/ problems. once i had rationalised a problem/bad ezperience it was boxed up and put back in storage somewhere in the depths of my brain a bit like a filing system.

if it works then use it
