Is the shadow under the street lamp a real image or a virtual image?

The shadow under the street lamp is different. Shadows are formed by people blocking some light and forming some dark areas. The real image is composed of actual light and can be accepted by the light curtain. Virtual image is formed by the reverse extension and convergence of light. Shadow is not formed by light gathering, and it does not belong to real image or virtual image.
