A Green Iguana's Human Bed

Iguanas may enjoy sleeping with their humans because of their strong social bonds and need for warmth and security. In the wild, iguanas often sleep in high, safe places like trees, away from predators, but in captivity, they might seek out warmth and comfort from their human companions, who provide a sense of safety. Sleeping near you might mimic the warmth and protection they would feel in their natural environment. Iguanas are also quite intelligent and can form strong attachments, so if they associate you with comfort and security, they may prefer to rest close to you.
