Dream about blue wallpaper symbolises support and your ability to ask for help when you need it. Perhaps you are the one being labeled. You already have the solution to a problem. It is about realization of your goals or dreams. You are being hammered or intoxicated.
Blue wallpaper dream is sometimes your inner and hidden state and being. You are overanalyzing a situation. A person was mentally deteriorating. This dream represents the depth of your subconscious. You are struggling with keeping your animalistic desires in check.
If you dreamt about blue wallpaper:
Someone is pulling your chain in the workplace today. Be careful of retaliating in too harsh of a manner. You may find that your hand gets slapped harder than the person who started the whole thing. Take the high road and you will remain on top.
