runs wild

Escapes all restraint

Runs wild describes something that grows, spreads, or behaves without control or restraint.

Plants run wild when they grow unchecked: The ivy runs wild along the back fence.

Children run wild when unsupervised.

Imagination or speculation runs wild when it ranges freely, often excessively: Rumors ran wild after the announcement.

The phrase suggests untamed energy—sometimes liberating, sometimes problematic.
