I would only take that seriously from thoughful, detail-oriented, intelligent people who have demonstrated critical introspection abilities before. Otherwise I'd assume they are making it up post-hoc. People often swear up and down in witness testimonies about what they saw and it just turns out to be complete post-hoc fabrication of their mind, even if it seems true to them. Similarly I think they post-hoc think it was a big brown table but this is like a language model completing the sentence.
It's been shown how in split brain patients the language center of the brain can make up totally unsupported justifications for actions that "explain" its experience, fully unrelated to what actually happened.
