The “Greys”
Reported entities & creatures
Beings described as small, grey-skinned, big-headed and with large almond-shaped black eyes. This image took hold in popular culture after Betty Hill’s account and especially from the 1970s-1980s (book covers, films). Historians note that this iconography preceded a large share of testimonies of the same type.
