What is the name of this series?

I'm looking for a series that stars a girl who is transported to a magical world through a diary of sorts. It was available to stream on Netflix and Prime Video. The only thing I remember is that she always has purple hair and has some kind of adventure. The last episode I remember is about dreams and everything in the world fades away.

What I'm not sure about is that, as far as I know, she always lives in a tree house and has a lot of friends. I don't know anything else.

Series that aren’t:

• Mia and me

•True and the Rainbow Kingdom

• Gabby's Dollhouse
