A very big dimension. Bigger than your universe, smaller than the box. It's just nice.
Don't pressure yourself, there's people caring for you, like me. Don't get drenched thinking you are meaningless.
You're just here to have a nice peaceful time, right there in the Very Big. You could get out, get in.
What ever you do, just have nice day. Well not day, Very Big is just very dark. You could explore, though.
It contains your universe and House. Y'know, house. Just a nice, relaxing, universe.
