This time of the year, between Pesach and Shavuot we count days in Sfirat Haomer.
It has 49 days (7X7), same as the time we spend in the Bardo (according to Tibetan Buddhists) after death.
There are many similarities in this experience: Each day, some other "mind-film" from our past, is being screened, and we totally live the emotions it brings up.
(It could also be viewed as the final term tests of main issues in your life. Concentrated patterns and  familiar situations that present themselves as an opportunity for resolution.)
Every day brings a different quality of the Sfirot (That represent specific energies), a certain combination. The order of which is written in the book of Zohar. For instance: The worst quality used to be Lag Baomer (Din Be-Din, "Din" being a harsh energy), until Rabbi Shimon Bar Yohai transformed that day when he died like a martir. (That's why now it's considered to be the only date when you can get married and have a Yom Tov). He took the bad Karma on himself because he was such a Zadick, spiritually evolved.
And, as you know, each second is an opportunity. At any second you can realise that you're in the Bardo, and the veils of illusion will disappear, like turning on the light in a dark theater where the film is screened. This realization is an opportunity to get out of the Bardo. At any second we can get enlightenment, only we get carried away by the illusion. We get tempted by it, totally identify. We get so engrossed by it, that we forget that it's a movie, and that we can get out at any time.
It's truely amasing to notice how the old patterns return. If you direct your attention and awareness, and it's a matter of "fine-listening" (like "fine-tuning") you may

 notice familiar situations. I know that when I realise it in the middle of something that feels like a "nightmare", recurring scene, the realisation can wake me up: It fades away I get what they call A-Ha moment, and then I'm free. Funny..
