Hi gwhutton
According to some, your unconscious beliefs are reflected in your reality so you don't really need to search for them. Look around at what you experienced as clue. I have came across the following explanation which does not directly address your concern but nevertheless may shred some light:
"...The uncovering of limiting beliefs is not to be applied as a witch-hunt. It is often by looking for limiting beliefs that limiting beliefs are created in the first place. This is what many teachings fail to point out. Do not create the belief "I have a bunch of limiting beliefs I need to uncover before I can be myself." Limiting beliefs are noly to be looked for when you are in a low or problematic state or experiencing the repetition of a problem. As we mentioned, you are mostly not looking at your beliefs but as them. That's why it's helpful to wirte them down. If you write them out on paper, you have an easier time veiwing them. Since your beliefs are reflected as outside reality, you can use outside reality to determine what you really believe. You don't have to dig into the distant past to find them. Look around at what you are experiencing, and it's obvious what you believe. Presupposing that you have a bunch of deep, super-subconscious beliefs to figure out or release before you can move on is a very limiting belief in itslef. Believing you have to uncover something you don't know is yet another limiting belief...."
