Been getting this a lot lately actually. Started doing sessions out in the woods near my place and a few times now the responses have come back within maybe half a second of me finishing the question, which rules out bleed-through from ambient noise in my experience.
The one that got me was when I asked "is anyone here with me tonight" and what came back sounded like a male voice saying "always have been." Played it back maybe twenty times. Could not find a rational explanation for it.
What I want to know is whether anyone has noticed the response times getting faster over multiple sessions with the same location. Like does whatever is producing these get more... practised, for lack of a better word. Or is that me projecting patterns onto random noise.
Anyone keeping proper logs with timestamps on this? Would be curious to compare methodology.
