1. 68% of people in one study experienced "phantom vibration syndrome". It is a sensory hallucination where you mistakenly think your phone is buzzing. 2. Alien hand syndrome is a rare neurological disorder in which one hand functions involuntarily, with the victim completely unaware of its actions.
In alien hand syndrome the individual tends to display more sensory deficits as they dissociate themselves from the hand and its actions, frequently remarking on the hand's behaviour as if it does not belong to them.
Alien hand syndrome is the misattribution and belief that one& hand does not belong to oneself, but that it has its own life.
