So, a Dreamer hops over to the Dream Sphere by making use of their Sandglass! By making use of it to transform, the Dreamer is automatically shifted away from the Waking World and from the POV of outsiders, they straight up just vanish into thin air. Rather than popping back where they vanished from, once a Dreamer leaves the Dream Sphere, they'll reappear back in their bed as if waking up from a long sleep... though whether 'their bed' is actually the bed they think of as being their own or just the last bed they slept in is up to players to mess around with based on what would make for the funniest bit.
