To dream that we are being exhibited probably means that our spiritual identity is being questioned. When we are at an exhibition we are being presented with new ideas. Psychologically we do not appreciate being inspected like an exhibit, so this type of dream may show some disquiet about the way people regard us. An exhibition hall tends to be a place where similar objects are grouped together, so from a mundane perspective would denote such a situation in working life, possibly uncovering a difficulty with being managed too closely.
