In the end of TBBT, Sheldon wins a Nobel prize. At the time, Missy was separated from her husband and had an unwanted pregnancy (so things were not going so great for her). However, in S4 E11 of Young Sheldon, Sheldon says that "Only one of us (him and Missy) has a Nobel prize. All the other one (Missy) has is a loving family and friends."

This must mean that 1) Sheldon is narrating after the events of TBBT, and 2) that Missie ends up with a loving family and friends after the events of YS, GMFM, and TBBT.

Missy really had an unfairly hard life in YS, GMFM, and TBBT, so I'm really happy that she gets a happy ending.

1. Kitty has clairvoyant powers. She can hear the narrators, and was the only one to remember what happened when Brooke turned back time in one of the webisodes.
2. Kitty has the power to shape-shift. Not only do we see Kitty’s mom turn into a cat, we see Kitty shape-shift herself by magically changing her hair and outfit in Spring Unsprung.
3. Kitty has the power to turn invincible, which Raven doesn’t.
4. We see in Way to Wonderland that Kitty has much better control over her powers than Raven. Raven is talking about how hard it is to use to her powers properly, and then Kitty just casually teleports in like it’s nothing. Kitty also doesn’t lose control over her powers when she’s upset like Raven did in Dragon Games when talking to her mom in the mirror.
5. Kitty’s powers don’t take control over her or affect her ability to think properly like Raven’s did in Way to Wonderland.
6. Kitty’s powers are neither malevolent nor benevolent, so her powers don’t backfire on her like Raven’s do when she uses them for good.
7. Kitty is originally from Wonderland, so her powers don‘t fade when the tie between Wonderland and the EAH world is severed like Raven’s did in Spring Unsprung.
8. Kitty is able to communicate across dimensions, such as by contacting her mom (who was taking a nap under Wonderland) while she was at the Spring Fair in the EAH world by drawing a smile in the air. In Kitty’s diary, we also see Kitty and Maddie communicate telepathically.
9. Like Raven, we see in Kitty’s diary that she has the ability to bring along other people when she teleports. She does this to save Lizzie Hearts.

It must be different from the sleep dancing thing because Baba Yaga refers to that as “enchantments“ instead.
