Well I'm not the best person to answer this as I only read for myself, but till someone more useful chips in
I'll add my 2c as this does happen to me.
You doin fine, Scarlet! I occasionally also experience this phenomenon when I read for myself, and surely the same principles apply in a counselling setting.
After acknowledging that this most likely means I am the key controlling factor in the situation,
Alright, there's a thought. That would be
one of the things to look out for, anyway. Isn't it known that our thinking influences our experiences quite a lot?
if I still want answers, I find it helps to change tack completely for a few minutes. In my case this can be distracting myself completely from the cards and question by watching a few minutes of rubbish television... in a reader-querant situation this could take the form of chatting away with them about something completely different that won't evoke the same feelings.
There's another thought. Make them focus on something else to momentarily break up their mental fixation. Yay!
The second option I use is to do a mini one or two card reading on something completely different... again, ideally something that doesn't illicit the same feelings in the querant.
Same principle, different application. Gotcha.
After doing one or both of these things I find I can quickly take a left turn back into the original question with fresh eyes and sort of catch the cards/querant when they aren't looking
Wow, Scarlet, you seem to be a real expert on the topic! Thank you, I will bear all your advice in mind next time I happen to be stuck with this.
ETA: My instinct on the reasons would be: sometimes this may be someone blinded by their feelings or on occasion it could be a case of the 'splodger', who projects their feelings overwhelmingly to the room and everything/everyone in it. My mum's a classic for this.
That's an interesting observation too! Last time I repeatedly experienced this, it was on a party, with a rather forceful woman around (she really reminded me of the Thoth Queen of Swords) who was disclaiming Tarot for herself. I instinctively tried to screen my querents and myself off, but I suspect she could have acted as a "splodger" nonetheless.
