If it is a deam than what this will be the 2nd dream idea for Season 2 right?
Yes, if you aren’t counting Aurora and Snow and Henry and Charming going to the Red Fire Room.
It’s worth noting that dreams are a common trope in TV and literature. Dreams often show our deepest fears or desires. I wouldn’t expect them to go anywhere on this show and I don’t consider it “repeating” just because they are a useful plot device.
We have had 3 people lose their memories – David, Sneezy, and Bella (2 people in Season 2)
We have had 3 people accused of killing someone – Snow, Regina, Red (2 people in Season 2)
Now we have 2 people who had dreams – Regina, Bella, and now ? (2 people in Season 2) ❓
Yes, I think that’s right. But they all serve different purposes. So Sneezy loosing his memories was to show what happens when someone crosses the town line. Belle loosing her memories has a lot to do with Rumple learning how to win her back. It may feel the same but it’s serving a different agenda.
