- A covering, or something that covers something up
- A veneer or mask
- A fresh start or new beginning, since a wallpaper gives walls a "new look"
- An attempt to control one's appearance or the impression one makes
- A mood or setting for the particular dream
consider the color, condition, and other attributes of the wallpaper (dreary, happy,
torn, pristine, childlike, conservative, etc.) and what they signify to you.
