Hi Harry

Your fears are still identifiable, they don't have to be fears of a physical object to use the tape successfully. Paul asks on side B to know "That signal" the stimulus which causes you to mistakenly use your imagination in a self-defeating way to create uncontrolled fear. "That signal" could be just a thought of a possible future event. For example with fear of rejection, the thought of a future possible event could be "They won't like me" with accompanied imaginings, or "I'll be a problem for them to have around" with accompanied imaginings. Or in the case of being found out if you have a certain secret, the thought of the future possible event would be "Oh dear, they're gonna find out" with imaginings. "That signal" is different for all people, it is the very first stimulus, which could be a thought, which then triggers fear and unrealistic, self-defeating thoughts.

Hope this helps Harry.

Kind regards.
