I forgot to post this the first time I watched this episode, but I’m watching it again right now, and I’ve always wondered…
What kind of memories would you find OUTSIDE OF the Mystery Shack?
Think about it. Inside the Shack, they must have checked hundreds of doors before finding the code to Stan’s safe. Not counting the vending machine memory, none of them noticed anything particularly strange about the memories.
But fans of Gravity Falls know that “Stan is not what he seems”
You can clearly see the branch of a tree coming in from the right of the frame, and when they are all walking there are tree shadows behind them.
My guess is that the dream forest of Gravity Falls is full of information too secret to even be shown in an episode. It’s probably filled with stuff about the Order of the Holy Mackerel and Bill Cipher.
Or maybe that’s where Stan keeps his porn. Who knows?
