According to Greek mythology, Hypnos is the god of sleep. He is described as a calm and gentle deity who brings rest and peace to people. Interestingly, the word “Hypnos" comes from the word "hypnosis". In Roman mythology, he is also called “Somnus”. Hypnos’ mother was Nyx, the ancient goddess of the night, and Erebus, the god of darkness. It is therefore obvious why he plays an essential role in the day cycle. His twin brother is Thanatos, the god of death. The two of them work closely together and help people to avoid suffering and die peacefully while they sleep. 

Homer, Iliad 16. 453 ff : [Hera speaks about his son Sarpedon's death :] “But after the soul and the years of his life have left him, then send Thanatos, and Hypnos, who is painless (Hypnos), to  carry him away".

Hypnos is described in various myths living in different places, such as in the underworld where his brother rules, on the island of Lemnos or in a dark and musty cave. The god of sleep is married to Pasithea. Pasithea is one of the youngest Charites, and the goddess of meditation and relaxation and thus symbolizes the connection between sleep and rest. Hypnos and Pasithea had many children, known as the Oneiroi. Oneiroi represented dreams. The most famous among them is Morpheus, who is known for his ability to shape dreams according to the desires and fears of mortals.

Other children are Icelus, who is responsible for dreams in which animals appear, and Phantasus, who conjures up dreams with inanimate objects. The Muses regarded Hypnos as their best friend! Muses are the goddesses of creativity in literature, science and art. This connection could help people by giving them inspiration through dreams. Overall, Hypnos plays a crucial role in Greek mythology as the god of sleep. By providing both the gods and humans with a peaceful sleep, he ensures that they remain healthy. He also has the power to heal and inspire through the world of dreams.
