[GAMEPLAY] Playing in a different dimension?

I don't know how to explain what's going on. My ping appears fine so I don't think its lag. Essentially at random moments a few things would happen...

1. The sound would stop.
2. I can move my guy around, and it appears like everyone else is moving- but what's going on ON screen isn't consistent to what's really going on.
3. I can see life disappear or people hitting 0hp but they won't die.
4. I can cast spells and abilities but I'm basically guessing.

The screen isn't locking up per se- but I can't tell what's going on.
I tried lowering my settings to the lowest.
At first I thought it helped, but then another game later I had it happening again even more frequently.
My internet appears to be fine, so I'm not sure the cause.

I think tell when I'm back in the "normal dimension" when the sound starts playing again.
Then all the pieces on the board are where they truly are.
