From The Journey (Brown 1992) As cited in Chapter 14 of Lenses by Kraus (2008).
This is Tom Brown Jr. sharing how "Grandfather" described an inner vision:
"The tightness in your gut when you tried to remember but could not was your Inner Vision trying desperately to talk to you. . . . That tension, that deep gut feeling, is exactly how our inner vision tried to talk to us. Thus when the answer is finally found on a logical level, the gut reacts with the release of tension. Your greater self is so relieved that you have found an answer, an answer that it knew all the time."
Something else shared in the book is by Gendlin (1996, p.37-38).:
"the odd feeling of knowing you have forgotten something. . . . You are troubled by the felt sense. . . . Notice that you don't have factual data. You have an inner aura, an internal taste. Your body knows but you don't. . . . Then suddenly, from this felt sense, it bursts to the surface [remembering what you forgot]. Somewhere in your body, something releases, some tight thing lets go."
