7 Freud’s theory of dreams Freud believed that nothingwe did occurred by chance; every action and thought is motivated by our unconscious at some level.While we try to repress our urges and impulses they have a way of coming to the surface in disguised forms – such as dreams.
8 Freud understood the symbolic nature of dreams and believed dreams were a direct connect to our unconscious.Freud was preoccupied with sexual content in dreams.
9 Thoughts repressed during the day also have a way of being fulfilled in your dreams. Freud believed that every imagery and symbol that appears in a dream have a sexual connotation. Anxiety dreams were seen as a sign of repressed sexual impulses
10 Adler’s theory of dreams Alfred Adler ( ) believed that dreams should be brought into our waking life and interpreted in order to understand our waking problems.He saw that you can draw resources from your dream and incorporate them into solving waking problems. Adler saw dreams as a way of overcompensating for your shortcomings in your waking life.
11 Activation-Synthesis Model States that dreams represent random and meaningless neural activityStates that the pons sends out millions of nerve impulses and the cortex tries to make sense of these signals.May create feelings, emotions, random movements, perceptions and meaningless images

There are oral mouth devices (that help keep the airway open) on the market that may help to reduce snoring in three different way. Sleep Apnea is a progressive condition (gets worse as you age) and should not be taken lightly.
16 Types of Sleep apneaObstructive Sleep Apnea is the most common type and is due to an obstruction in the throat during sleep. The pauses in breathing may be approx. 10 to 60 seconds between loud snores. The narrowing of the upper airway can be a result of several factors including inherent physical characteristics, excess weight, and alcohol consumption before sleep.
17 Types of sleep apneaCentral Sleep Apnea - caused by a delay in the signal form the brain to breath . With both obstructive and central apnea you must wake up briefly to breathe, sometimes hundreds of times during the night. Usually there is no memory of these brief awakenings, however, the person will report being very tired. WHY???
18 NarcolepsySymptomsExcessive sleepiness. -Temporary decrease or loss of muscle control, especially when getting excited. -Vivid dream-like images when drifting off to sleep or waking up. -Waking up unable to move or talk for a brief time.
19 TREATMENT: There is no cure for narcolepsy TREATMENT: There is no cure for narcolepsy. The excessive daytime sleepiness may be treated with stimulant drugs. Basic lifestyle adjustments such as keeping a good sleep schedule, improving diet, increasing exercise and avoiding "exciting" situations may also help to reduce the effects of excessive daytime sleepiness and cataplexy.
20 How much sleep does a person need? Insomnia-Difficulty falling asleep -No problem falling asleep but difficulty staying asleep (many awakenings) -Waking up too earlyHow much sleep does a person need?Enough to feel alert during the day. Typically 7 to 9 hours (varies from person to person) of good quality sleep.
21 Transient and short-term insomnia generally occur in people who are temporarily experiencing one or more of the following:- stress - environmental noise - extreme temperatures change in the surrounding environment - sleep/wake schedule problems such as those due to jet lag - medication side effects
22 Treatment of insomniaRelaxation Therapy. There are specific and effective techniques that can reduce or eliminate anxiety and body tension. As a result, the person's mind is able to stop "racing," the muscles can relax, and restful sleep can occur.
23 Sleep Restriction. Some people suffering from insomnia spend too much time in bed unsuccessfully trying to sleep.They may benefit from a sleep restriction program that at first allows only a few hours of sleep during the night. Gradually the time is increased until a more normal night's sleep is achieved.
24 Reconditioning. Another treatment that may help some people with insomnia is to recondition them to associate the bed and bedtime with sleep.For most people, this means not using their beds for any activities other than sleep and sex (some experts even say using the bed for sex can cause performance anxiety which could lead to insomnia).
25 Reconditioning Go to bed only when sleepy. If unable to fall asleep, the person is told to get up, stay up until sleepy, and then return to bed.Avoid napsWake up and go to bed at the same time each day.Eventually the person's body will be conditioned to associate the bed and bedtime with sleep.
26 Pseudo-insomniaThese are people who often do, in fact, get enough sleep, but they tend to misjudge the amount that they got.This is often because of REM deprivationHealthoogy
27 Night terrorsUsually occur in stage 3 or 4 – occur during 1st part of nightChild usually displays a piercing scream, followed by sudden wakefulness and sympathetic nervous system is activatedThe child is very difficult to calm down and may need several minutes to awaken
28 Night terrors occur in approximately 3-7% of children between the ages of 4-12 Seems to disappear by adolescence but may require therapyOften do not remember what it was that they were dreaming about
29 NightmaresOccur during REM sleep, so we tend to see them occur more towards the 3rd and 4th cycle (not stage) of sleepWhen the person awakes, they often remember the nightmare in detailAlthough the nightmare ends upon waking, the anxiety often persists – often due to anxiety
30 Sleepwalking (somnambulism) Usually occurs in stages 3 and 4 (deep nRem) and consists of getting up and walking while sound asleep.Sleepwalkers generally have poor coordination, are clumsy, but can engage in very limited conversation and have no memory of sleepwalkingAshley remind me of my kids sleepwalking
31 Sleepwalking is more common in childhood, however, there are some adults who may sleepwalk, although this may be due to sleep dep., stress, or mental problems.
32 Some tips to better sleep Give yourself "permission" to go to bed. As hard as it may be to put away your "to do" list, make sleep a "priority." You'll thank yourself in the morning. Unwind early in the evening. Try to deal with worries and distractions several hours before bedtime.
33 Develop a sleep ritual. Doing the same things each night just before bed signals your body to settle down for the night. Keep regular hours. Keep your biological clock in check by going to bed around the same time each night and waking up close to the same time each morning – even on weekends.
34 Create a restful place to sleep Create a restful place to sleep. Sleep in a cool, dark room that is free from noises that may disturb your sleep. Sleep on a comfortable, supportive mattress and foundation. It's difficult to sleep on a bed that's too small, too soft, too hard, or too old.
35 Exercise regularly. Regular exercise can help relieve daily tension and stress – but don't exercise too close to bedtime or you may have trouble falling asleep. Cut down on stimulants. Consuming stimulants, such as caffeine, in the evening can make it more difficult to fall asleep.
36 Don't smoke. Smokers take longer to fall asleep and wake up more often during the night. Reduce alcohol intake. Drinking alcohol shortly before bedtime interrupts and fragments sleep.
