It all appears to be in Finns imagination, as he and Jake frequently reminisce about "Mom" and how she took care of them before the mushroom war.
Uh, Finn was raised by Jake's parents after they found him abandoned.
Oh yeah, seen that one. I have seen them remembering Mom though, I think it was when they were attacked by those little sweet thingys and Jake and co pretended to be hurt in battle against them so's not to hurt their feelings.
But back to subject, it dosnt bare any resemblance to Star Wars.
