Anyone else had a reading where the medium knew something they absolutely shouldn't have?

Had one years ago in Stratford, bloke mentioned my dad's nickname - a daft thing my mum called him, never written down anywhere, not the sort of thing you'd find online. Threw me completely if I'm honest.

Still sceptical overall. Cold reading explains maybe 80% of what mediums do and I'll die on that hill. But that one detail genuinely puzzled me and I've never fully shaken it.

Anyone else had that specific experience where it's not the big dramatic stuff that gets you, it's some tiny throwaway detail that lands wrong? The small things are harder to explain away than "someone you loved has passed" type nonsense. Would love to hear other examples, particularly if you've actually tried to debunk it afterwards.

Yeah that sort of thing is hard to explain away isn't it. Had a reading in Manchester about 15 years back, woman told me the exact street my nan grew up on - not the area, the actual street. I'd never told anyone about it, wasnt on any paperwork she could've had access to. Still think about it now.
