Researchers at Michigan State University and the University of California, Irvine asked 104 individuals to look at pictures of a crime being committed. One group was allowed to sleep whilst the other was made to stay awake overnight.
Those who were sleep deprived and read false information about the scene were more likely to report remembering the false information compared to those who slept overnight.
It's thought that anything less than 5 hours of sleep each night can lead to the formation of false memories.
Probably best not to rely on an insomnia sufferer as a witness, then.
