For some people fear might be real, for other it might not. In my opinion fear is not quite real.
Reasons:
Fear is usually produced by a trauma or a traumatic experience. It might have happened when you were young or when you were old.
Fear is usually cause by our brains, let us take watching a horror movie for example, after you watch a horror movie you feel scared at whatever was happening in the movie is going to come to life.
The last reason is on why people say fear is real but it is not, ok let say you ask someone what is their biggest fear, and they answer losing their family, or dying. That fear is caused by bad experiences like I said before this could be trauma, most people who are scared of losing someone important to them, have experienced really bad things in the past.
In conclusion fear is not real, but instead a mirage of illusion that our brain creates.
