Psychology says people who are scared of closed spaces, spiders, crowds or any other such thing aren't always afraid: What this behavior reveals?

Psychology says people who are scared of closed spaces, spiders, crowds or any other such thing aren't always afraid of the object or place itself. Their fear can come from the possibility of losing control, being trapped, facing harm, or being unable to manage what happens next. Psychology explains how the brain connects certain situations with danger and creates an alarm response.
