So which sounds better?

She was oblivious to the world around her, "Dash!" Or so it seemed.

Or

She was oblivious to the world around her, or so it seemed. "Dash!"

2107663 I say go with option 2.

That would depend on the context. Here(without context) I would say the lower one.

The first contains an error and is ugly (you need a dot, not a comma). The only true answer is #2. And, dare I say, it would be better with a new line after "seemed", if "she" designates Dash.

The second, and only the second.

Definitely number two.

I believe that some formatting is needed here. Having it in a line is unsightly, and it destroys the possible effect.

I believe 2107782 has the right idea. The way he wrote it is exactly how I would. I would do what he did here.

2107782>>2107897 Now the question is how to continue, is the "...Or so it seemed" a stand alone line or a part of a bigger paragraph?

One or the other. It depends on what you plan on doing with it. Having it as a single line builds up a certain amount of tension by making it read slower. If you make it a part of a larger paragraph, then things transition far more smoothly.

Generally, action is separated in different paragraphs. One paragraph per action, and generally, start a new paragraph whenever a significant action occurs. The yelling seems action-y enough.
