Yeah this has happened to me a fair few times actually. You go back through the recording and the response lines up with something you asked maybe 30 seconds later. It's properly weird when you first notice it.
My working theory is that whatever's communicating isn't experiencing time the same way we are, which sounds mental but its the only thing that makes sense to me logically. Either that or there's some kind of pre-cognitive element on our end that we don't fully understand yet.
Had a session at a site in Coventry last year where I got what sounded like a name, thought nothing of it, then about a minute later I asked if anyone there had a connection to that specific family. Gave me chills when I played it back.
Anyone else keeping detailed logs of when this happens? Would be useful to see if there's a pattern, like whether it occurs more during certain conditions or with certain equipment.
