I have those types of events often, but the actual feeling of deja vu has been absent for me for a long time. I always likened the "double events" as you say to the outcome of dice rolls. When the power of numbers converge, the dice roll doubles, or in the case of other things, you get a coincidental match of one thing to another occurring at the same time. I remember being told in school to open our books to some particular page number and just randomly opening the book to the exact page number the teacher said. Randomness isn't very random it seems. The universe does like order rather than entropy.
