We don't often take a close look at our bedrooms. I know I am in this room when I go to sleep and when I get up. Maybe come back later in the day to change clothes for going out somewhere. So I found this interesting and most of it we do in our room. When I go to bed I just don't want to be surrounded by clutter, it makes it hard to sleep. Here is the advice in this article.
"Ideally, your bedroom will be a sanctuary that allows you to rest deeply. It's amazing how our belongings can "talk" to us."
Don't have piles of clothes on the floor or bedroom chairs or other surfaces.
Don't have paper clutter: mail, newspapers, books, folders
Trinkets on shelves, nightstands. These can be knickknacks, perfume bottles, etc. Knickknacks drive me nuts, one always leads to another and another.
Too much furniture
Stuffed dust catchers such as too many pillows or heavy curtains. At one time a decorating trend was to have all sizes of throw pillows on beds after it was made. They always had to be moved during the night.
