Have you ever woken up feeling like you've been to the end of the world and back, without ever getting out of bed? Or perhaps you may have realized all your worst fears while you were sleeping? In that case you were probably dreaming. Dreams are a “series of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep” (The American Heritage High School Dictionary, 2004). We each have three to seven dreams a night, but it has been estimated that we forget up to 95% of them (Stevens 2011). While no one really knows why we dream every night, it's very likely that it's a way for our brains to help us solve problems. Brainwaves Dreams are exceptional and complicated phenomena that occur while we sleep. But sleep itself is also a mystery. There are still some things we know, though. For example, there are four distinctly different brain waves produced by our brain. Beta waves are the fastest and most active when you are awake and alert. They might be busy working on math problems or playing soccer. Alpha waves, the second fastest, flood our brain when we are relaxed and at ease, perhaps during a long car journey. Theta waves occur when the body is doing something repetitive that doesn't require much concentration, such as running laps. Finally, delta waves, the slowest of all, are produced during deep sleep. Sleep phasesThese waves are also active during the different sleep phases. In the first phase, also called light sleep, which occurs after breathing becomes shallow and we begin to fall asleep, the most common waves found in the brain would be theta waves, but there would still be a large amount of delta waves as well. These continue throughout... in the middle of the paper... or the sewing machine, the idea of ​​threading the thread through the tip of the needle came to him from a nightmare in which members of a native tribe were chasing him with spears which had holes at the end. Robert Louis Stevenson also got the idea for his book from a nightmare. At a time when he was almost penniless, Stevenson dreamed of a scene that would later become the basis for his famous novel, The Strange Case of Dr. Jekyll and Mr. Hyde. Dreams are incredible events that happen to each of us every day. single night. From lucid dreams to nightmares, they've had a huge impact on life as we know it today, but we've barely scratched the surface on how they work and what they mean. Maybe it's our brain trying to solve the problems in our life, or maybe it's just a mess of thoughts and experiences from the past few days. No one really knows, and that's why they're so compelling.
