//Hypognosis, the recording was a piece of music appropriate to some happy news we'd just received which wasn't yet widely known. There are no practical jokers.//
Thanks Naomi. Just acknowledging that I saw this reply. I thought the thread had fizzled out and then stopped using AB for several days. A few more pages have been added, in the meantime, including the above. Reassuring to note that a possible angle had been tackled. I also like the additional details from a few messages further on.
Anyway, I was waiting for a suitable moment to drop the word 'priming' into the discussion but slaney has beaten me to it and both Naomi and other contributors have averted it by way of story details specifiying that no priming occurred.
At least, none that they knew of or participated in personally.
Just remember that all haunted locations necessarily have neighbours, or chatty locals who may bring it up as the opening conversational gambit at the slightest sign of passing tourists or furniture being moved in...

Dr Susan Greenfield did some experiments with electrical brain stimulation and reported quite vivid sensory responses. It would be intriguing if there were underground/overground power lines, nearby or geological features aligned in such a way that one property is affected but not the ones next door.
Positional specificity is a feature I find intriguing. 'Ghosts' always seem to 'go with a place'.
But if they wandered around and people didn't "compare notes" effectively enough, how would we prove the above notion false?
