The Science behind Dreaming


Some people think dreams are a way of predicting the future. Some say that dreams are a way of expressing your real thoughts and opinions. But who is right? Have you ever woken up from a deep sleep and wondered, Was I dreaming? Or have you ever questioned what a dream really is? Well the definition of a dream is a series of thoughts, images, and sensations occurring in a person’s mind during sleep. Dreams are pretty much a series of images and stories that our brains create while we are asleep. Most dreams can be vivid, sad, happy fearful, or angering. There are many reasons for why we dream but scientists do not now for sure which reasons are correct.

What is a “Nightmare?”

Let’s start off with the most memorable dreams people have, also known as nightmares. Nightmares are disturbing dreams that seem realistic that can easily awaken you from a deep sleep. You are probably wondering what is the cause of these terrible dreams?  The causes of a nightmare is when your brain enters a stage of REM or rapid eye movement. REM is a kind of sleep that occurs in intervals during the night and is characterized by rapid eye movements, more dreaming and bodily movement, and faster pulse and breathing. This then triggers neurons in the brain to become rapid and your brain creates terrifying images. Shortly after, images are imagined when we are asleep that can often be terrifying or frightening. These images can lead you to become terrified after you have awaken from a deep slumber. Night terror’s are also common, they can happen when people see a scary image in their brain and wake up with their heart pounding against their chest scared to death. Most of the nightmares that people have had are  very traumatic experiences. These dreams can occur exactly like the trauma, those with PTSD(post traumatic stress disorder). In conclusion nightmares are frightful but it is just your brain messing with you.

What is the Cause of Happy Dreams?

Have you ever experienced a dream that was so happy and fun, that you did not want it to ever end? This is caused because it indicates that you are happy with your place in life and that you are in fact happy. If you have more emotion filled dreams, this may be caused because you are having a hard time in your life. Sometimes during a happy dream it is the opposite of what you experiencing in your life, this tends to happen because your brain in creating images to make your stress levels, and heart rate decrease. These dreams make you feel like you are in a good place and shows that these things in your dreams make you even happier.

What is Lucid Dreaming?

Have you ever started dreaming and then later realised that you were dreaming? Or have you ever been able to control what goes on inside of your dream? This is a common situation called, Lucid Dreaming. Lucid dreaming is usually triggered by an inconsistency, such as if you are dreaming and you stop, to question your reality. During a Lucid dream you can create anything and nothing is out of reach, no idea, object or creature is too “out there.” After experiencing a few Lucid Dreams you will experience alterations to there perspectives, and that there is a lot in reality that you do not fully understand. Some people think that Lucid dreaming alerts us of problems that we will face so that we can work towards a resolution.
