Do all horses live in stables how do horses sleep?

Horses mostly sleep standing up. Horses do lie down occasionally, but most of the time they feel too vulnerable to do so. You will be more likely to see a horse lying down to sleep in a stable than out in a field. Horses live anywhere from stables to pastures, to islands. Also, some miniature horses have also been known to live inside their owners' home when used as therapy horses.
