Here is a recording of a whole Zoom appointment with a client. 
(The client's video is removed to protect her privacy, but you'll hear her voice)

Past Life Regression sessions are unpredictable. You can do an amazing job, but it still may happen that the client won't give you much to work with. Just be patient and pay attention to every word your client says. Even if the client won't give you anything at all, you still can help your client with the issues they complained about. 

Remember that Past Life Regression is a tool, even when the regression doesn't go as well as you would like, it's still a great tool for helping your clients.
