Your Dreams are not Private Anymore. Scientists can look into it

    Yes, you heard me right. Your dreams are not private anymore. Pretty soon, people can see what you saw when you were in sleep. The Japanese scientists have figured out a way to record and interpret what you dream about just measuring your brain activity.

    The Japanese scientist team (Tomoyasu Horikawa, Yukiyasu Kamitani) has developed an artificial intelligence algorithm to record/store and visualized it later. They can put recorded data into an algorithm that can reconstruct your dream so that it can be played back to you when you are awake.

    Before moving forward, let me describe some information about dreams and some interesting facts on the dream.

    What are dreams?

    Dreams are stories, images, and sometimes conversations that our minds create while we are in sleep. It can be funny, romantic, entertaining, disturbing, frightening, etc. dream is a succession of images, ideas, emotions, and sensations that usually occur in the mind during a particular stage of a dream without our control.

    There is no proper explanation for the dream. The researcher believed that dreams help us process emotions and make sense of the world; that’s why most of your dream contains real-world contents.

    If you think you haven’t seen any dreams, then it suggests that you don’t sleep well, or you can’t merely recall your last dream after wakeup.

    Facts on dreams

    • Around 95 percent of people forget what did they dreamt about when they got of bed.
    • Blind people dream more with sensory data compared with sighted people.
    • Every human being dreams (except for some psychological disorder).
    • If you thought you don’t dream, then you forget that dream after waking up.
    • You can have 4-6 dreams in one night.
    • Men generally have more aggressive emotions in their dreams than the female.
    • Not all dreams are in color; they can be in black and white.
    • Scientists believed that animals have a dream.

    On moving forwards, the Japanese have invented a kind of dream recorder/the keeper machine. You don’t have to worry about forgotten dreams. You can playback your dream when you wake up from sleep.

    Working Mechanism

    Brain waves are generated within our brains when continuous electrical pulse/signal passed from each neuron. Brain waves are electromagnetic radiation wave that oscillates at 10-100 cycle per second. These neural patterns are related to what a person visualized.

    Brain Waves
    Abstract brain wave concept

    When you imagine an object, your brain produces a neural pattern. If anyone can record that neural pattern, then the machine can reconstruct that object easily.

    Tomoyasu and Yukiyasu had developed a machine-learning algorithm to construct visual from your brain waves data. An algorithm use brain data to correlate with appropriate images. Your dreams are not private anymore as the machine learning algorithms will reveal our secrets.

    Japanese scientist Tomoyasu and Yukiyasu experimented with people without any physical or psychiatric disease, without sleep disorders, without a bad habit of taking alcoholic beverages before sleep or smoking.

    The Japanese scientist then hooked test subjects with an electroencephalography (EEG) machine and then fell asleep within an fMRI machine. Scientists used the EEG reading to identify whether test subjects were on the dreaming phase or not. Scientists repeated nearly 200 times for each subject.

    Scientists recorded the signal when characteristics EEG signature occurred. From 200 awakening processes, visual objects, scenes were manually extracted and mapped into WordNet. Scientists labeled fMRI data with a visual content vector.

    Scientists found out that discovered certain types of objects were common, correlated with brain neural patterns. They used the internet search engine to look for images that roughly matched the items from the subject’s dreams.

    The machine-learning algorithm used scan data from test subject MRI scans and generated videos from the image dataset.

    In a nutshell, I will say that your dreams are not private anymore, and someone can look inside your dream. The research still is under study and experimentation. It might revolutionize how dreams are interpreted and understood by people. Researchers have suggested that machine learning algorithms can predict better with time as technology improve over time. In no time, people can understand what blind, deaf people are dreaming. It will be technical advancement to understand differently-abled people. It will be a milestone about technology in history.
