The way you said this "Since they only have beingness in your reality due to our vibrational activations of them" it implied otherwise, thanks for clarifying your thoughts.
Even if you do not share a 'mutual vibrational space', they still exist in reality, in everyone's reality, for we are all One. The way you worded it sounded like if they are not 'vibrationally activated' in 'your' reality then they don't have beingness. They still have beingness and in your reality, but you are just choosing to not interact with them. That's very different from suggesting they do not have beingness outside of your activation of them.
