False memories can sometimes be shared by multiple people . One prominent example is a 2010 study which examined people who were familiar with the clock at Bologna Centrale railway station , which had been damaged in the Bologna massacre bombing in August 1980 . In the study , 92 % falsely remembered that the clock had remained stopped since the bombing , when in fact , the clock was repaired shortly after the attack . Years later the clock was again stopped and was then set to the time of the bombing in observation and commemoration of the bombing
