Dang it. I had this dream earlier this month (on the third) and just realized the correlation. I was having trouble in waking saying them backward, so I quickly made a mnemonic device that I called Jason.

^^D isn't in there. Because of December. And the rest I remember easily, so I decided with Jason I could easily go backward. That night I had this dream. Didn't recognize the connection till now. :/.

Spoiler for Jason is kind of a Douche:
