“I have a Jimmy/James asking for John”.
So why did this psychic believe they were getting messages from your, presumably still alive husband?
And how many people would have been able to make a connection to 3 very common male names?
And if you hadn’t made a connection you’d have been offered something else until you did, and then that connection would be the thing you remembered and would recount here.
Or another way of thinking about it - the first 9 people they tried those names on came up with nothing, the 10th person was you and you’ve remembered it ever since.
Collecting elastic bands to make a ball? One of my sons does that, I think it’s quite common with kids, worth a stab at using it as you only need to score a few hits for people to believe you have a gift, they will forget everything else you said that was wrong.
The difficulty with some stories though is that you’re just not getting all the information you need to make an educated guess as to what really happened. One thing that is certain though is that our subjective recollection of events is very unreliable. Just ask someone who practises slight of hand how easy it is to distract and confuse people. The difference is, with a magician you are in on the joke, you know it is a trick, no matter how impossible it is to work out how they did it.
