Psychologically: In dreams blockades appear every now and then if the dreaming must make a special effort to overcome an obstacle in his process of development. In the dream she can appear in all sorts of forms. It is possibly experienced as a material blockade - possibly as an object about which one climb or around which one must walk around. Mentally, for example, if one is not able, to speak or to hear, or spiritually a blockade can also express itself. Spiritually: At the spiritual level a blockade can be a preventive measure, a warning.
