I'm having real trouble understanding speech (bits are just noise, like a foreign language I don't speak), and lately I've been hearing people say random words that make no sense, that they insist they never said, even though I definitely heard it. My parents think it's hilarious and keep taking the mickey, but it's not funny

Today my parents were talking in the car, but I wasn't really listening until I heard my Mum say "killing a bouncy castle", which immediately got my attention. So I asked them to repeat what they'd said and it was about a truck in front of us. So I asked what they'd said about killing a bouncy castle and they just started laughing.

And a couple of weeks ago, I had a voice mail from the GP surgery off a woman called Louise. So I asked my Mum if she knew who Louise was, and she said no I don't know a Louise there. And I asked Dad the same thing and he said the same. So they took me to the GP surgery and I asked the receptionist if I could speak to Louise, and my parents both said that I had said that I got a message off Nicola. Apparently they said that I'd said Nicola to each of them, and they had said Nicola back to me, so I'd heard Nicola 4x yet definitely heard Louise each time. That is also hilarious to them.

I'm either hearing words/noise that make no sense to me like it's in a foreign language, or I'm hearing words that people aren't saying! And despite it being highly frustrating and upsetting that I'm not understanding conversations and people are telling me they never said things that I most definitely heard them say, my parents think it's hilarious

ETA: this is happening A LOT, but those are the only 2 examples I can think of right now.
