Thanks for your comment. I think I understand, but I guess I look at shared consciousness as a continuum from "obviously exists" to "highly speculative". In its more obvious form, you and I probably have some sensing hardware in common (not 100% sure since I don't know you, but maybe we both have eyes, for example) so we may share light-consciousness, sun-consciousness, etc. Through one very simple lens humanity can be seen as a mesh sensor network that shares the "consciousness" product. In this way I would expect that any form of life with e.g. a nervous system and means of communication (or even just reaction which leads to chain reaction) can at least in basic ways share its consciousness. On the speculative end perhaps you'd have phenomena like shared intuitions or visions; however that's still a gradient; in some fields like Jungian psychology these are seen as products of a long and convoluted physical sensing processes, not as magic, for example.
