When it gets to the psychological, it gets hard. Everyone is different.
In my case, I browse my personal library and just feel like rewatching that movie. For me, that's for enough as a mechanism. I don’t need further “artificial” rituals.

Again, IMO you will have to create for yourself the experience that is “magical” to you specifically. It can be difficult to do it on your own (you may feel like cheating yourself). That’s why I suggested the social aspect that can makes it feel more "genuine".
