The Alien Hand Syndrome is a condition where a person finds their hands or limbs acting on their own. Someone who experiences this tends to feel that one’s hands or limbs are rather possessed by an outer force. It is generally said to affect the left hand. The syndrome occurs in some cases as a result of trauma to the brain, a brain surgery, sometimes also after a stroke or because of a brain infection. The person affected may do a certain action or manipulate objects without any intention of doing so. They might feel the sensation in the affected hand but might think that the hand does not belong to them as they have no control over it or its movement, that it is the hand of an alien.
