Caveat also let's be very sure these are solely telepathic voices , those hearing these have been evaluated by licensed psychiatrists to be free of mental health issues.

I've heard telepathic messages and telepathic voices since a long time back , I haven't to date heard anything else other than regular "human sounding" voices , no animal effects , no demonic or angelic effects - nothing , that's also probably because I do strict one-to-one telepathic experiments with the other person I have engaged and choose by myself to shut other things out.
