It's difficult to give you the solution without the example.

It relies on the human memory being pretty bad at recalling events after you leave the situation. I would wager that however you remember the situation (if it's you that you're talking about), then that's not really how the events played out.

I know that's probably difficult for you to believe because you were there, but tests have shown this happens all the time. People make recordings, then after listening to them back have a completely different perspective of what was happening.

You went to a clairvoyant for a reason. That's the key element.
