The Strange Self-Motion Illusion
Anomalous experiences tend to jolt one out of one’s comfort zone, tell us interesting things about how the mind works. A vivid déjà vu, strange coincidence, or unexpected illusion can all be automatic attention-grabbers. Some of the oddest experiences are visual. When a large part of the visual field moves, the viewer can momentarily believeContinue reading “The Strange Self-Motion Illusion”
