Scientists have worked out why your eyes move when you’re dreaming. Scientists have known for decades that the rapid eye movements (REMs) that occur during sleep signal that we’re dreaming, but what do the individual eye motions really represent? It’s long been hypothesised that each movement of the eye reflects new visual information in our dreams, and now for the first time researchers have demonstrated that this is actually the case. According to a new study by researchers at Tel Aviv University in Israel, each flick of the eye that occurs during REM sleep accompanies the introduction of a new image in our dream, with the movement essentially acting like a reset function between individual dream "snapshots".
