Déjà vu about déjà vu

I felt like I had already read this article when I read it:

About two-thirds of people experience at least one déjà vu in their lifetime, and if you have had one you are likely to have more. For reasons unknown, the incidence of déjà vu decreases with age, rises with education and income, and is more common among people who recall their dreams, who travel, and who hold liberal political and religious beliefs.
