By that I mean basically unexpected oases in your life where and by whom you feel nurtured and restored and just safe in the moment?
For me, it was a woman at work who became like a mother to me and I’ll think a bit more about physical spaces but that is a very important aspect also
Try not to say your home space cuz that should be a given. Think outside the crib
No, all I can say is when I was a child my mother and occasionally grandmother had that effect. It started to get less effective during my teens and it’s certainly no longer a thing anymore. As for other sources that truly nurture AND make me feel safe, no, I can’t think of a single one. I’ve had plenty of people taking nurturing and protective roles in my life but I wouldn’t say their effect was of full restoration and complete safety. Same goes for places. Something is always amiss or not enough for full recharge and safety.
