I'm looking for an old anime, can anyone help, please?

It's an old (what I think to be) anime. It's about a sleeping/comatose girl with long brown hair wearing a white gown/dress. She's being 'driven' around by a floating white pod shaped like a water dinosaur. (think like Lapras from Pokemon) The pod is fleeing from a group who's after the girl for her mysterious powers. On the way it gains aid from allies and new friends. The pod also provides database information to complement the story. Nearing the end at one point the girl awakes from her eternal slumber, and shows her mysterious powers (one being telekinetic powers she uses to throw rocks and rubble (she was also wielding a sword at that time)).

I can't provide any names, and some of the allies/friends have an animal-like appearance, showing multiple species in that world. They also traverse multiple types of environment. (deserts, swamps, mountains, meadow, snow etc.)

Please, if anyone has an idea, that would be perfect.

Thanks in advance!
