First welcome to the RWBY Wiki. Second it's an interesting theory you have there.

It's possible that the Red trailer was a dream but I doubt it based on the fact that Monty said the take place before the story, so it's implied that these events actually happened and weren't dreams.

Second I would think it's more about Ruby feeling worried for Jaune because he's being bullied and not saying anything to someone.

There are my thoughts do with them what you will. Hope to see you around the wiki Mr. Knight.
