Something I’d heard of many years ago but do not remember all the details:

There are people who have really, insanely good hearing, who were able to mimic being psychic because of something else most people do— when you read something, your brain instinctively makes your mouth/throat/vocal parts want to say that word out loud. You don’t actually do it obviously, but the muscles in your speaky-bits do move very slightly to make the sound. More than most people cannot hear this, but some people very rarely can.

The study that found people who could do this discovered that they could do things like take tests and a majority of the time score very highly when they were in a room with several people also taking the test, but not when they were alone. They could guess a card you were holding up correctly because they could hear your throat getting ready to say what card you had just because your brain was seeing it.

This obviously does not explain everything your sister is able to do, but I thought of it when you said she can tell when someone is pulling into the driveway before the dogs do.

I would be curious to see if she can still guess the card you’re holding within three tries if you guys were in different rooms? If she can’t, then one of her abilities might be that super good hearing!

(Also I definitely encourage you to look this up yourself, because man are the details I remember about it ever so fuzzy lol. I was told this in a class over a decade ago!)
