Smells and Tastes
Years ago my spouse and I were meditating together and at the end of the meditation we kissed and he tasted like chocolate. I asked him what happened in his meditation and he reported how he was in a house and saw some chocolates on a table so stopped and ate one. He had that chocolate flavor and smell on his lips and tongue.
Sounds
When I was taking an acupuncture class, the teacher reported how you can feel the Qi at an acupuncture point. We then were each instructed to locate an acupuncture point on a fellow student and see if we could feel the Qi. What I noticed was I could HEAR a swooshing sound whenever I was at an acupuncture point. I could hear the sound of the energy flowing at a point.
Images
When I started doing energy work to help people heal, I noticed it was as if their bodies were sending me images about what was going on in their body. I could see the image of the joint, the blood vessel, the organ with the problem and/or the solution which was needed.
All of these types of non-physical messages are a type of telepathy.
