Seeing things get narrow in a dream is also a very powerful experience. If you are dreaming in an experience that suddenly gets narrow, pay attention to what is happening around you. Your subconscious in this case is trying to hone your eye in on a very specific detail. Alternatively, you may be feeling restricted or confined in some area of your life.
You may be in the wrong job, the wrong relationship, or even in the wrong home if you experience this in a dream. When you experience a narrowing of sorts in a dream, it usually means one of two things. You need to open your funnel vision to hone in on some details, or examine the big picture a little more closely.
