Get involved deep by another force while you were by standing I’d assume.

Driven underground makes more sense. Unless you literally mean 'the bus was driven under the bridge' or similar.

Any context? It sounds pretty much like something being driven from beneath. Perhaps a metaphor for something hidden.

can you give us the whole sentence? i'm having a hard time putting it into a sentence honestly. the best i can think is it's a slightly poetic way to say bringing someone down, in other words causing someone to feel hopeless or emotionally defeated

This may refer to something like for example a protest group subject to government suppression who while not destroyed might be forced from public view and continue in a covert way. They could be described as driven under. But really your question requires more context to answer well
