I don't believe telepathy is possible with the dead. What are you communicating with? Animals...yes you can communicate with feelings but the dead have lost the ability to send messages. Brain activity is needed for telepathy. I don't know what Tyler Henry does because I haven't figured out or decided what I think he does yet but I would not call it telepathy. I would call it communicating with spirits but why focus on the dead now? What is the purpose other than to provide living people with closure when someone dies.

How is it possible to use telepathy with ETs? They would need to be familiar ETs because otherwise they would not be familiar with your frequency. how did you meet them?
