Homichlophobia

Nebulaphobia (also termed homichlophobia) is the morbid fear of fog. This fear is due to a negative experience involving fog, like an automobile accident. Some sufferers may fear supernatural entities like ghosts or magical creatures hiding behind the curtain of fog.

Nebulaphobia can be treated by teaching patients all about the fog, especially that it is a natural (not supernatural) phenomena. But many may prefer professional treatment, like counseling, support groups, prescribed drugs, or hypnosis.
