What does it mean for a fairy to sleep on her back?

Sleeping on the back of a fairy is a relatively relaxed sleeping position, which means that a person lies flat on the bed or floor and sleeps on his back, similar to the posture of a fairy. This posture is usually considered as a bad sleeping posture, which will lead to health problems such as poor breathing or soreness.

Some people think that "the immortal sleeps on his back" means that the immortal lies on his back in the clouds to rest or sleep. This statement may have something to do with the immortal image in the ancient legends of China. Some people also interpret "the immortal sleeping on his back" as a state of practice, which refers to a person's posture during meditation or practice. At this time, sleeping on your back may represent a state of inner meditation, or it may represent sleep and tranquility.
