It could start by causing small annoyances like moving around the room at night, but then escalates to more dangerous things like attacking people. Also, the idea of a group of people getting lost in a fog - covered forest where the trees seem to have a life of their own and there are strange noises all around can be very terrifying.

The forest seems to feed on their fear and pain.

How about a small town that has been cursed? The townspeople start to transform into grotesque creatures at night. Their eyes turn yellow, and their teeth become long and sharp.

One idea could be a person who moves into a new house and every night hears strange scratching noises from the attic.
