Do あなた think it's possible it could be another one of Reginas 'nightmares??'

Well nothing is impossible so I'm not going to flat out say no. But I do think it actually happened in her dream she woke up before anything too bad happned to her. Also I don't think the writers are that repetitive.

i dont think so cause there's another sneak peek of her in jail and she's again trying to see if she can use magic when rumplstiltskin comes in telling her that magic here is different
