Hi Esi, I've experienced this a fair bit in my dream realms! I've wondered about this, too.
Perhaps this could indicate an aspect of Self making contact with us in a way that seems familiar to us. Eg, taking on the form of friends/family/acquaintances. The image-shifting might take place because in our mind-self, we might still value validation/acceptance from others over validation/acceptance from our intuitive selves. Or maybe we're still working on reconciling with the illusion of separation and trying to accept Oneness as a concept and way of being. So then the dream could be reminding us that the *form* doesn't matter - what matters is the connectivity that we recognize when we're in the presence of each other, or in the presence of our own full being.
Hope that sparks something helpful!
