Dreaming is a series of thoughts, images, and sensations occurring in a person’s mind during sleep. Continually, each night everyone has delusions of dreams. Although one may not recall his or her dream, he or she can have a multitude of various dreams per night. This development is likely to be personal to people; therefore, each particular dream contains some sort of connotation. As of now there is no definite scientific explanation as to why people dream. People experience numerous types of dreams; being the most common types of dreams one can have are lucid dreams, nightmares, and recurring dreams. Lucid dreaming is a part of the development of dreams that can appear anytime but certainly in stressful periods. This condition of lucid dreaming is the scientific proven ability to become “self aware” in one’s dream. When one is lucid dreaming the person dreaming is actively awake during ones dream. Therefore, they are fully aware they are dreaming and have the ability to control their actions. In addition lucid dreaming is scientifically proven (Hearne). The first scientific proof of lucid dreaming came about in 1975 from a British parapsychologist, Dr Keith Hearne (Hearne). He recorded a set of predetermined eye movements from Alan Worsley with an “electrooculogram” (Hearne). This was a basic communication between the man’s dream and the real world outside the dream. In addition, a study in 2009 showed a person who was experiencing a lucid dream record brainwave frequencies up to 40 hertz. The normal brainwave frequencies while dreaming is anywhere from four to seven hertz (Hearne).  Moreover, Lucid dreaming has multiple physical and mental benefits. For example, lucid dreaming can help someone get over a fear or phobia. Lucid dreaming can also help someone deal with grief by rekindling with a lost loved one. Overall, lucid dreaming can help one improve life skills and can make one feel the exhilaration of life. Another type of dream one can have is a nightmare. Nightmares are a type of sleep parasomnias, which are dreams that cause anxiety and fear in the one dreaming. Nightmares usually happen when one is in a “deep sleep.” They are almost never lucid dreams, because the one dreaming is unaware they are dreaming, adding to the terror of the dream. Moreover, nightmares are a common and natural thing as long as they do not significantly interrupt ones sleep patterns (Freud). There are many known causes as to why people experience nightmares. For example, they tend to happen when one is dealing with stress or a traumatic event. Nightmares can also result from sleep deprivation or sleep and mental disorders. Nightmares are hereditary. Therefore they are more likely to happen to a person if one’s family members have a history of nightmares or other sleep parasomnias.  Ultimately nightmares are extremely common. They affect up to as many as 80% – 90% of people in one’s lifetime (American Sleep Association). Nightmares begin as early as three years old and can last until death. Although nightmares happen to almost everyone, they tend to be more common in females. Dr. Jennie Parker did a study that showed not only do women have more nightmares than men, but womens’ nightmares are more emotionally intense as well (Parker)Recurring dreams are another common type of dream one can have. They are when one has the same dream over and over again. Recurring dreams tend to go hand in hand with nightmares. Recurring dreams are usually troubling dreams and tend to be nightmares the majority of the time. Recurrent dreams occur between 60% and 75% of adults, and are more frequent in women than men, just as nightmares are (Zadra).  When one has a recurring dream it usually means there is something in one’s life that they have not acknowledged that is causing stress or anxiety. For example recurring dreams revolve around what is going on in one’s life at the moment. If one continues to dream about the same situation that means it is not getting resolved in real life. Recurring dreams can last a short period of time, however depending on the situation they can last a lifetime (Zadra). Nonetheless, recurring dreams have been proven to help real life situations. Most recurring dreams revolve around current life problems. Therefore, dreams can both help one prepare for and find a solution. For example, if a student dreams of failing a test, they are then more motivated to prepare for the test (Arnulf). Add conclusion sentence.Individuals experience multiple types of dreams; such as lucid dreams, nightmares, and recurring dreams. Humans have more than one dream per night. Although there is not a scientific explanation as to why we dream, we do know that there are multiple types of dreams. These dreams, no matter if they are lucid, nightmares, or recurring all have deep meaning to each individual.
