©John Wiley & Sons, Inc Huffman: Psychology in Action (8e) Sleep and Dreams: Insomnia: persistent problems in falling asleep, staying asleep, or awakening too early Sleep apnea: repeated interruption of breathing during sleep Narcolepsy: A rare sleep problem in which people suddenly fall asleep no matter what time it is or where they are.

Types and Causes of Insomnia Temporary Insomnia: Brief period of sleeplessness caused by worry, stress, and excitement.  Avoid fighting it and read a book, for example, until you’re struggling to stay awake. Chronic Insomnia: Exists if sleeping troubles last for more than three weeks.  Adopt regular schedule; go to bed at the same time each night, for example.

Some people use sleeping pills to cope with insomnia but many psychologists believe that the safest, simplest, most effective ways of overcoming insomnia do not involve medication. ©John Wiley & Sons, Inc Huffman: Psychology in Action (8e) Types and Causes of Insomnia

Nightmares We have all had nightmares at some point of our lives. These dreams are quite normal. Nightmares are a subcategory of dreams. A nightmare is a dream including frightening and/or emotional content. When having a nightmare, it is possible to wake up in fear. You tend to remember nightmares and its details because of it being frightening. Sometimes, the images from a nightmare might stay with you throughout the day. One reason for nightmares may be a way of our unconscious to get our attention about a problem that you have been avoiding. Nightmares serve an important purpose in showing you what is troubling and causing you problems. Discussing, analyzing, and understanding your nightmares can lead to a solution for some problems.
