To your vicinity, people’s uncomfortable truths about themselves are in plain sight within their mind’s eye, incapable of avoiding them, almost as if someone forces them to confront their biases and self-deception. You gain an insight into their unconscious truths and use it to your advantage or theirs if you’re more benevolent.
When asked about something, they’ll tell you with the utmost truth as they lose their capacity to lie to themselves and others around you.
This can be therapeutic for some as it is crushing for others.
