2. The tone, character or mood of an environment created by watching horror films.
3. The creepy or unnerving feeling a person gets when surrounded by a large mass of people, such as in shopping malls, bars/pubs and crowded city streets. Most easily recognized when a person realizes that everyone is moving and talking but no one is really doing or saying anything.

3. There's a certain zombiance to holiday shopping. It really freaks me out.
