Mystery surrounds the case of a soldier who began to see the world upside down after being injured in battle.

Patient M was shot in the head by a gun-launched missile while fighting on the Valencian front during the Spanish Civil War in May 1938.

After being found lying on the ground, the wounded soldier miraculously survived without the need for any operations or special care.

But when he regained consciousness two weeks after the explosion, he began to see things upside down in certain situations.

Born in a village in the Ciudad Real region of Spain, the soldier saw a terrifying retrograde world when he rested, without major stimuli.

The objects appeared in triplicate and tinted green while his hearing and touch were also reversed.

Dr. Justo Gonzalo remained in contact with patient M throughout his life
