Pimples
Internal negative feelings that are felt within will be exposed to others. Pimples inform the dreamer that these unconscious emotions that relate to your image and communication with other is infected. To notice the pimples on your back becomes a metaphor for this issues being something behind you, covered up, or not noticed. When the dreamer either pops or squeezes the puss out of the pimples it represents a removal of this internal build up within. Abscess show that this is a build up that has been accumulating for a long time.
