Centipede
Many small reactions to one thing — overcommitment of small parts.
A centipede in a dream is the dictionary's image of many small reactions happening to one cause. The centipede walks with many legs at once; the dream often appears when one situation in your life has triggered many small responses in you, each of which is taking a little energy.
Where you often see it. A centipede across a bathroom floor. A centipede on a familiar surface. The dream uses the centipede for many small reactions to one thing — overcommitment of small parts to a single response.
What it is not. A centipede is not always disgust. The dictionary often reads it as the dreamer's many-jointed reaction to a single trigger.
Related in the dictionary. Read centipede with insect, spider (its calmer cousin), and any scene of over-articulated reaction.
