Goodnight is a farewell message to say bye or bid adieu to someone at night. Goodnight is a way to wish someone a happy and sound sleep. A sound sleep is much more refreshing than a discordant and disturbing sleep in which you are bothered with all sorts of negative emotions. Wishing someone goodnight can be a great way to wish someone a sound sleep and a great morning, thereafter. A sound sleep and a peaceful mind are quite interlinked. You can only sleep soundly if you have some peace of mind. Work towards getting that peace of mind.
Wish someone goodnight and pray for their sound and peaceful sleep. You are only praying for someone’s betterment by wishing someone a good and sound sleep. You should say goodnight before going off to sleep. Wishing all your loved ones goodnight before going off to bed is a healthy and good habit.
