If I move in with my boyfriend, I'm gonna use one of his 5 bedrooms as a black room. I'll paint all the walls and ceiling black, get black floors, black curtains and window shades, black furniture etc. For lighting, I'll use purple lights. I saw a similar design model in Ikea and I fell in love with it. It had a bachelor pad feel to it, but I'd use it as my own private space. Play whatever music I want, drink, practice belly-dancing, and whatever else I feel like doing. No one would be allowed in without my permission. If I'm having a bad day, I'd just go into the room and kick sobriety to the curb all while not knowing whether it's day or nighttime outside. 

That's roughly what I have in mind anyway.
