Why does purple prevent nightmares?

There is no particular color, whether purple or any other, that can prevent nightmares. Nightmares are produced by each person's subconscious mind, expressing the dreamer's problems and fears. However, any charm in which a person sincerely believes - a dream catcher, a nightlight, a statue of a saint, nighttime prayers, etc

• can help ease tensions and encourage peaceful sleep.

because purple is a natural absorbent of nightmares, its only logical to know that purple should be used worldwide as a anti-nightmare dosage.
