I am actually in the process of making my "dream room" from my garage so this is kinda fun seeing I really haven't shared much of it et lol. Well first off it's a big room and then there is like a storage area that is being formed into my sleeping area. (It's big enough for a bed and a couple of dressers.)
Sleeping area - It will have my hand crafted purple&black/green&black dressers in there along with a small twin bed that has my red&black satin bedding on it with 4 huge fluffy pillows. The walls are painted in large spirals with little creatures in them, and the spiraled colors are white and black, and the creatures are whatever color I make them. The ceiling will be black with grey clouds on it, and I'll be cutting the designs of the glow-in-the dark bits myself for it so there will be stars and faeries and such.
Living area - The walls will be individually painted fantasy/horror murals. Very psychedelic room in a whole. The ceiling will be a very elegant night sky with a harvest red moon. The furniture I'm in the process of building the couch, love seat, and big comfy chair will all be done in either retro or tie-dye coving, and the table will be in a hexagon shape with glass in the middle, and then the chairs will have the same cushion colors as the couch and such. There will be a tv stereo system in there along with my computers and such.
In a whole it's all very basic other than the paintings and such, but this is a room(s) that are like just for me and such seeing I can't do it to my current room lol.
