The snake that sucks its own tail the Ouroboros is a potent image of spiritual completeness and will appear as we become more spiritually advanced. Emotionally we all have needs which are left over from childhood. These may be unfulfilled desires or the need to be wholeand complete. This need can surface in dreams as sucking something. To be conscious of sucking in a dream suggests a return to infantile behaviour and emotional dependency. Sucking a lollipop alerts us to a need to bring ourselves some sort of comfort. Sucking a finger symbolizes the primitive urge to suckle.
