I have an interesting book at home about Feng Shui - there is a whole chapter about using it at bedroom - i will check that out and let you know! Using Feng Shui might be really good idea - maybe the energy of the room (and whole home) will get better.
PS Have already checked - bed in the bedroom shouldn't be placed with foot of the bed in front of the door (Chinese believe that this is the way how dead people are ging away from the room) and also in front of the window. And as bedroom supposed to be a place of peace and quite where we should rest there shouldn't be too much things in there and all of them shouldn't be placed with edges towards the bed. I hope it is a bit of help for you.
