So I'm submitting one for a verse that I had attempted to do calcs for. There's a case for either layered Sleep Manipulation or layered Dream Manipulation, or both depending on how you want to interpret this. The entire second game in the series is exactly that!:
Tlaloc (the main antagonist) is the cause of everything in the entire game, as noted by one of Tlaloc's nightmare sheep appearing in reality in the ending.
So, the way it works is there are two layers...
Reality-->Layer 1 (Tak's dream reality)-->Layer 2 (The Dream World)
In the opening, we see that Tlaloc (who initially played off the guise of a Juju prior to revealing himself after you defeat the Dream Guardian) had Tak trapped in The Dream World (Layer 2) for 16 days. Tak wouldn't get out of the Dream World until he did Tlaloc's favor the first time, after which we see Tak's first awakening in what is supposed to be reality, but is actually Layer 1 of the dream. A good chunk of the game involves Tak going between Layers 1 and 2, and it would be shown that Moon Juju (pretty much the big Juju that all the tribes seek the favor of) couldn't really last long in Layer 2 before she had to go away. Tak would later wake up in reality after, again, 16 days in the ending of the game, with this reality legitimately being reality.
