None.

A woman repeatedly has an issue where she is bleeding from her neck at night, and freaking out on her husband or other house staff after the fact. Fairly bloody.

A vampire man has a stake pounded into him by another man. Scene is brief and not bloody.

Not much.

Nothing major.

A dead boy torments his mother after she resurrects him by playing a wicked spooky game of hide and seek. May be frightening for some.
