Vera Farmiga is another actress who would be good. She has a very intense look in her eyes. At the beginning of a ghost story, she could use that intensity to set the spooky mood. For example, in 'The Conjuring' series, she starts off the story with a sense of dread and determination that hooks the audience right away.
The ability to convey fear or unease is crucial. When an actress can show that she is on edge or sensing something strange, it makes the audience feel the same way. This can be done through body language, like fidgeting or constantly looking over her shoulder.
An actress in a ghost story should have great acting range. In a ghost story, there are usually different emotional states. She might start with a sense of normalcy, then progress to confusion when strange things start to happen, and finally reach extreme fear. So she needs to be able to transition smoothly between these emotions. Also, she should be able to hold the audience's attention even when there are no dialogues, just through her expressions and movements in the spooky settings.
