Are dreams real?

 
Dreams consist of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep. The 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. Scientists believe that other, non-human mammals, as well as birds, also dream. Dreams can last for a few seconds, or as long as twenty 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, two hours of it is spent dreaming. Scientists at Boston’s Harvard Medical School say they’ve made the stunning discovery that dreams are not, as once thought, a series of abstract sensations, images and sounds that occur during sleep, but rather demonstrably real events that take place in an alternate universe that can only be accessed during certain stages of unconsciousness.
In a study published by scientists, detailed how they monitored a number of participants during various stages of sleep, and gave them complex tasks, such as bringing objects from the dream world back to the ‘real’ world. They said it first became apparent that dreams were real when subjects successfully managed to retrieve a number of items, including a comb, a lantern and a baby dragon.
Kevin McCaffrey, a neuroscientist and researcher who helped conduct the study, said that anyone was capable of retrieving objects from dreams, so long as they concentrated “really hard.”
“What people haven’t realised until now is that this alternate universe that we might call Dreamland, is actually a very real place that people do go to when they sleep,” he said.Well as usual there will always be mixed reaction as to whether dreams are real or not because some dreams do come true so we'll just have to continue read articles and draw our own conclusions.
