Smooth Plier in dreams
A gripping tool — extending your hold on something slippery or hot to handle.
How smooth changes the reading
Smooth texture adds ease — the symbol's surface is in good order, the friction is low. The reading is more positive than the base; whatever the symbol stands for is well-handled at the moment.
The base reading of Plier
A plier in a dream is the dream's image of an extended grip — a way of holding what you cannot, or should not, hold with bare hands. The dream brings the tool when you are having to handle something difficult — a contested object, an unpleasant fact, a hot situation — at one remove. A plier closed firmly on its target is the dream telling you the grip is secure and the handling can begin. A plier that keeps slipping is the dream noting that even with the right tool you are not currently strong enough or careful enough to keep hold of the thing.
