You had that much access to the dream bubbles...?

[Okay, she's a little jealous about that. She can count the number of times she encountered the dream bubbles on the ship on one hand.]

Well, anyways, only you can open the door to your room! If you leave it open then other people can get inside, but so long as the door is closed, you are the only one who can get in. So yes, they are very private!

To open your door you just need to try and focus the thought of wanting to go to your room through your gem. That's how I do it, anyways.
