Young people experience déjà vu the most. Having said this, depending on how old you are, you may still have to wait a while until you have your first déjà vu experience. A very small number of people say they had their first déjà vu experience by the age of 6. More people report their first déjà vu experiences as having happened sometime before they were 10 years old. The reason it may take a while to have your first déjà vu experience is that you need to be able to work out whether the feeling of familiarity you have really is stronger than it should be. For many younger kids, this may be a tricky thing to do.
By the time you reach an age between 15 and 25, you will probably be having déjà vu experiences more often than you will ever have them after that. The number of déjà vu experiences people report steadily decreases after 25 years old. This is puzzling for researchers because we are used to thinking of memory problems increasing with age, not decreasing with age!
