also called omniphobia, pantophobia, or panophobia - a phobia known as a “non-specific fear”, i.e. a state of general anxiety or “the fear of everything”. Panphobia is often described as “a vague and persistent dread of some unknown evil” or “melancholia caused by groundless fears”. It is not registered as a type of phobia in medical references.
Etymology: from Greek πᾶν - pan, neuter of “πᾶς" - pas, “all” and φόβος - phobos, “fear”.
