Insomnia

A sleep disorder from a lack of sleep; insomnia is known to increase one’s risk of experiencing vivid dreams. Any changes to your sleep schedule, such as medications, or flying long distances (and going to bed at a different time) or getting less sleep than usual, can also increase this occurrence.

In a dream, sleeplessness means loss of a beloved, the death of a child, separation between lovers, or leaving one’s family and trav¬ elling to a foreign country.
