its sort of like, the few seconds before and after any given train of thought contains a bit of "cosmic metadata" that with enough experience and practice, you can learn to sort through and very quickly apply to your thought. think "how does this apply to the previous?"
also, it might be possible to slightly "read" a mind, though what im mostly talking about is reverse telepathy, maybe an encounter with God (aka the collective consciousness as it were)? say person A B & C (all having never met previously) are together, you are person A, wondering something about person B's intentions and C looks you in the eye and answers you, so you say to B "xxxxxxxxxxxxxx (deduced from the hints from C)" and they are dumbfounded

even works if only A & C are on LSD, or amongst certain folks, can happen naturally
