When I was a child, I was all about this anime movie and for years now I have not been able to find it nor pinpoint the title.
The description is going to be a bit ambiguous so just stay with me here and keep a very open mind. This is coming from the memory of a 5 year old.
Timeframe for when movie was made: mid 80s to sometime throughout the 90s
In the beginning there is a brunette little girl (maybe even a pre teen) that does not appreciate something in her life. I believe she gets upset with her mother and takes her for granted then runs outside to her backyard upset. There she encounters... something... a spirit... or animal. I can't remember but she is sent on a mission and it gets pretty hazy from there. I remember the end is her waking up in the backyard and it was all a dream and she runs back inside and hugs her mother.
No, it's not Spirited Away. Really.
