My ex-sis-in-law reads and has out-of-body experiences while reading. Reading does activate the crown chakra in all people as they associate to the mental imagery of the collective unconscious. They get better at this in adolescence. If needing to dissociate is high then, it can be too much a good thing.
Meant to have social connections during that time of development, but that was not safe for some of us or only with certain safe people for a specific, limited purpose.
I think this is part of the high intelligence that presupposes DID. High imagination and intellect allows the child and later, adult, to do things to cope that most would not do. In fact, I don't see any need to pathologise this either.
It's not a bad thing inherently. Only that it may distract from other more healing ways of coping or getting needs met.
This is about meeting a felt need, only. Can you find 10 other ways to slake that thirst for a positive guardian? Can you write him or her into a novel? Can you draw them? Can they be a favorite character from a series of books? Can they be found in parts of other people? Can they be in a role model?
I think 'normal' people find this need met in a real person at some point, and then go about finding elements in real people, as needed, but then also internalize this early on and don't need to find it in the external world as much, but have an easier time actually doing that, since it exists already inside, like a map.
For those of us who never had a real, good guardian, unproblematized, this is tricky at best. It is needed to spend time cultivating these things in the imaginal self prior to looking in the real world, and honoring whatever the self creates.
Value your creations. That is my advice.
