What kind of faster-than-light travel is this and is it at least plausible?

I've had a fairly complex world built up in my head for several years and finally writing a story in it. One thing I'm struggling with is explaining the galaxy's faster-than-light traveling. It's not necessarily hard science fiction, but not necessarily complete "ignore physics." In other words, it can bend the rules but not break them completely rendering everything we know wrong

Here's a general idea of how FTL works in my universe, straight from the source itself..

"Imagine this ship is space. The vast universe home to trillions." Kandra nodded, her mom continued, "How can you get from here into where your luggage is" Kandra looked up at her mom. "I don't know." "There's multiple options, you could walk back to where there's a service ladder or maybe a ventilation shaft, or you can dig a hole in this floor? What would be the fastest?" "I guess dig." Her mom smiled. "Right. What the warp drive does is essentially digs through the dark matter in space, making and filling millions and billions of holes per second. It's not instantaneous because we can't dig a hole through a planet or a star, we'd burn up or kill a planet. We can through dark matter. It's something light can't do." "So, we're smarter than light." ... One more pull back, followed by a woossh sucking sound, the most powerful vacuum in existence sucking them inside of it. The blackness of space became a blue tunnel as they entered what was dubbed warp space.

I've called it a warp drive, but I know that may not be the right term for what I am using. Essentially, how it is described and works is almost like a combination of a wormhole, a warp/subspace, or maybe a alcubierre drive? I've also got an idea in my mind about traveling through a fourth spatial dimension that cuts down the distance. One thing about my universe, because it becomes somewhat of a subplot is that time traveling is not possible and considered fantasy by the alien races (a human scientist is mocked for bringing it up and it drives other plot points involving human-alien relations)

Add: I am going to drop the dark matter explanation.
