Throughout my life, every now and then, I have "heard" a voice (never the same voice twice) inside my head. I have always immediately known that the "sound" was from inside, not outside, so I always have seen this as a kind of awake-dream-thingie. (About once a year, something will happen in a flash, and then nothing.)
No, I have never sustained any conversations with suchlike, but, YES, I can accept that other nervous systems also have this ability and that some folks got this to the max. But, geeze o pete, I pity those folks, cuz I 100% know that experiences I have had were very convincing -- the voices truly seem to be from another mind. I would be out there publishing books etc. too, if I had this happen to me in any sustained fashion. Yep. I. Would. I once had my dead mother's voice simply say the nickname she called me. BAM -- just my name spoken in her voice as if she was next to me. Nothing after that, but see? Once at teacher training, in a semi-dreamy state, I had a voice say, "That's all that you can transcend? Here's what I can do." And then, I DIVED INTO THE GOLDEN LIGHT OF PURE BLISS.....for about 30 seconds and nary another visit from "that guy." Truth: everyone has nightly dreams that contain astoundingly detailed scenarios with characters fully blown, furniture, clothing, weather, etc. We're all producing the equivalent of full scale Hollywood productions.....every single night. So channeling? Pish tosh! ANYONE CAN AND DOES DO THIS SHIT EVERY NIGHT...so how much notice should a "daytime dreamer" get? Answer: Not much. Anyone who's known Maharishi CAN DREAM ABOUT MAHARISHI. Now, show me a five year old kid from a jungle tribe in Brazil who convincingly channels Maharishi, and I will pay much more attention.
