Dream Imagery
Dreams are an enigma of the mind that has been a subject of study by philosophers, writers, musicians, phycologist, and almost every group of people for centuries. Trying to describe these thoughts that people experience when they are asleep is, to this day, remains a popular topic of discussion. The human mind, the very essence of what defines our individuality, is one of the greatest mysteries mankind has tried to wrap its head around. Aided with language, this natural inquisitorialness has lead people to talk about each other’s internal experience, study the behavior of others, and with advanced technological imaging, people have been able to unlock the physiological secrets of the brain. With all these advancements that have given people a way to

The pairwise decoding had an average of 60.0% accuracy with specific pairs having an accuracy up to 70.3%. The data that Horikawa and his colleagues found, showed that the patterns of activation was more telling about the information of the dream imagery, than the activity level seen in any particular area. They also found that the higher visual cortex areas of the brain had a higher accuracy in predicting the reported synsets. In the multilabel decoding portion of the experiment similar results were found, where the higher visual cortex areas were more accurate in predicting the visual imagery reports of the participant. They also found that the fusiform face area showed better performance with human synsets, and the parahippocampal place area showed better performance with place synsets. These finding match the normal response to direct visual stimulus that has been demonstrated in previous neuropsychological studies. Further analyzation of the data, especially sets that had a high score for unreported synsets, shows that decoding systems may be recording reported and unreported visual imagery
