For me? Grounded fear was yesterday when there was a spider appeared on my couch.So, is it how you react or how you want to react in the present?
When I'm round my parents? I know I'm not staying grounded (yet), there is rarely any reason to be afraid in the here and now, so when I (frequently) feel afraid in their company, that's not being present or grounded. That's trauma-brain messing with me.
