Football is not an Olympic sport, but it was a demonstration sport at the 1932 Summer Olympics.[1] The IFAF seeks recognition from the International Olympic Committee (IOC), which would be the second-to-last step to gaining admission to the Olympic Games themselves. It would take at least a decade to be admitted.[135] Several major obstacles hinder the IFAF goal of achieving status as an Olympic sport, such as the predominant participation of men in international play, and the short three-week Olympic schedule. Large team sizes are an additional difficulty, due to the Olympics' set limit of 10,500 athletes and coaches. These issues are similar to those that rugby union faced prior to being admitted into the Olympics in the form of rugby sevens, a modified version of the sport, but football also has the issue of global visibility. Nigel Melville, the CEO of USA Rugby, noted that while rugby union has a major international presence through the International Rugby Board, "American football is recognized globally as a sport, but it's not played globally". In order to solve these concerns, major effort has been put into promoting flag football, a modified version of American football, at the international leve
Dreams are successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep.[1] The content and purpose of dreams are not definitively understood, though they have been a topic of scientific speculation and a subject of philosophical and religious interest throughout recorded history. The scientific study of dreams is called oneirology. Scientists believe that all mammals dream, but whether this is true of other animals, such as birds or reptiles, is uncertain.[2]

Dreams mainly occur in the rapid-eye movement (REM) stage of sleep—when brain activity is high and resembles that of being awake. REM sleep is revealed by continuous movements of the eyes during sleep. At times, dreams may occur during other stages of sleep. However, these dreams tend to be much less vivid or memorable.[3]

Dreams can last for a few seconds, or as long as 20 minutes. People are more likely to remember the dream if they are awakened during the REM phase. The average person has three to five dreams per night, but some may have up to seven dreams in one night. The dreams tend to last longer as the night progresses. During a full eight-hour night sleep, most dreams occur in the typical two hours of REM.[4]

In modern times, dreams have been seen as a connection to the unconscious. They range from normal and ordinary to overly surreal and bizarre. Dreams can have varying natures, such as frightening, exciting, magical, melancholic, adventurous, or sexual. The events in dreams are generally outside the control of the dreamer, with the exception of lucid dreaming, where the dreamer is self-aware. Dreams can at times make a creative thought occur to the person or give a sense of inspiration.[5]

Opinions about the meaning of dreams have varied and shifted through time and culture. Dream interpretations date back to 5000–4000 BC. The earliest recorded dreams were acquired from materials dating back approximately 5,000 years, in Mesopotamia, where they were documented on clay tablets.[6] In the Greek and Roman periods, the people believed that dreams were direct messages from the gods or from the dead, and that they predicted the future. Some cultures practiced dream incubation with the intention of cultivating dreams that are prophetic.[7]
