Dreaming in the Womb - 33 Week Fetus

During the final phase of pregnancy babies spend about 90% of their time asleep, and when they sleep, nothing will wake them. One of the things revealed by the 4D scans is the fact that babies have REM, rapid eye movement sleep, a period of sleep where the eyes flick around behind the eyelids. Later in life we know this is an indication of dreaming. This gentle flicker of an eye could be a sign that the foetus, still with a month to go before even being born, is already dreaming.
