And guess what, horses can dream too . Horses can doze off and rest during the first phase , theslow sleep , when standing . They can do this through an amazing ability of the equine skeletal system. They possess a unique ability to lock their own limbs, particularly their rear kneecaps , in place, allowing their skeleton to stand upright without engaging muscles . This is called a brace and it is possible thanks to a special system of tendons and ligaments .
It is not for nothing that horses are able to rest on their feet.

SOME INTERESTING FACTS ABOUT HORSES
A horse cannot achieve REM sleep while standing because the muscles must be fully relaxed. Just like humans who have this sensation of falling and who wake up jerkily from time to time, horses also have jerks and move in their sleep. Control of muscle function is lost during REM sleep and even the dwell apparatus is not sufficient to allow the horse to relax as much. So how much of this deep sleep do horses need on a daily basis? Most experts say 30 minutes to three hours a day is enough for the REM stage. Horses only sleep so soundly during the dark hours after midnight, unless it is
Experts also agree that this REM sleep only occurs in brief periods , usually 10 to 20 minutes at a time. The reason for this is likely due to the horse 's anatomy and physiology , the restriction of blood flow to vital organs when lying down, making it difficult for him to lie down for a long time. A horse can usually only lie down for a maximum of 45 minutes at a time.
HOW LONG DOES A HORSE SLEEP?

If a horse does n't get enough sleep , the ill effects may not be visible for a few days, but it may eventually become irritable , moody , and even dangerous. In some cases, a sleep-deprived horse may even collapse in unlikely places, such as at a show. There are a number of documented cases of this.
Sometimes a horse does not get enough sleep. This can create a lack of sleep over time. this lack of sleep can come from several causes. Among these reasons are stress , isolation, noise , lack of safety in a new place, articulation problems, insufficient space to lie down and social insecurity caused by situations such as introducing a new horse to a herd or a new aggressive horse nearby. The effects of lack of sleep in horses are lethargy and extreme drowsiness which results in poor performance and poor attitude. REM sleep disorder is a condition in which horses wake up with excessive body movement, resulting in a sleep deficit. Other sleep disorders in equines include narcolepsy , when a fully awake horse suddenly falls asleep, and hypersomnia, which is excessive sleep. Either of these issues could be a sign of a neurological condition and should be checked out by a veterinarian.

If a horse is lying down during the day, it may just be basking in the sun, but if it becomes common, or if the horse is lying down for a long time, it could indicate a problem. Lack of sleep, colic and other illnesses can be to blame if a horse spends a lot of time lying down during the day.
