Why Staring at Nothing Makes You See Things

Cut a ping-pong ball in half, put the halves over your eyes, shine a soft red light at your face, and play quiet static. Within minutes, a lot of people start seeing things that aren't there. This is the Ganzfeld effect. In this video, we look at where it came from, what people actually see, the experiments that measured it, the competing theories for why your brain does this, a strange detour into telepathy research, and where the evidence is still fuzzy. If you sat in a Ganzfeld, what do you think your brain would show you? Tell me in the comments! #psychology #science #brain #ganzfeld
