Dreams by definition are successions of images, ideas, emotions, and sensations that occur involuntarily in the mind during certain stages of sleep.
Perhaps one of the most overlooked writings of our time on dreams comes from the ancient philosopher, Aristotle.
Simply entitled "On Dreams" by Aristotle, viewed sensory perception in dreams as a mode of qualitative change. Our senses are initially affected or aroused in the dream and will continue to be affected until there is something to disrupt the initial presentations. To explain it further, Aristotle gives the example of looking at the sun and looking away, after looking away, we still see bright spots in our vision containing the outline of the sun.
Furthermore,’ he says that the sensory continuum is greatest during times when the person observes a fast moving object such as a river. The thoughts Aristotle gives of perceptions in real life appear evident in dreams, as well. We know about the similar perceptions in dreams because of the many testimonials that people give today about the manner that they experienced everything in the dream.
To sum things up, our dreams are simply reliant on our perception of what’s going on around us. Therefore, it implies that humans with similar dreams (falling, drowning, blood, flying ... etc.) have similar perception, or at least a common ground.
