This sign can also be done with just one hand.
You can do it with either hand, on either side of the head. What I mean by that is you can place the back of your hand against the side of your head, or you can place the palm of your hand against the side of your head. Or you can do as shown here by placing both hands together and then placing them both to the side of your slightly tilted head. (Also, see "Go to bed." below)

Note: Some people don't like to see the sign "ROOM" initialized. Which is to say, instead of using "R" handshapes, they just use relaxed "B" (also called "flat") handshapes.
