Scared character post process

Hello fellow developers. I am finishing the demo of my horror game within the next month . I would like to ask you one question . The main player of my horror game is going to have a fear bar , which when its over 70% a post process is going to happen , and lose some health over time , playing heartbeat sound etc. I would like to tell me your opinions and how to achieve them on that post process. For now the post process is a simple radial blur . I am looking for special post process settings that are going to make it more atmospheric and scary. Thank you in advance

Hello VortXGaming,

It depends on you what settings you want to change. But I can show you how to change.
