This is a good skill but very different to my understanding of dissociation. In dissociation you are unable to even observe your thoughts or feelings and your brain may not even make memories in this state. It's a pretty severe coping mechanism.
When I think of that phrase I generally take it to mean something beyond your usual routine. So if you normally eat whatever you want, eating what you want doesn't count anymore because it's part of your baseline. Maybe going out for a special meal that's a bit fancier and you wouldn't do all the time could be considered treating yourself. Or just going for a walk in nice weather if it's not something you normally do. The main criteria in my mind is that you enjoy it and it's something you do for yourself beyond your usual life routine.
Sounds similar to me in some ways, I think a small group of friends like that is better though. A few of us a still quite close and catch up regularly so I call that a win vs being generally popular.
A larger group is a rumi-nation
