Not really. The horse could easily injure you should he kick. Even if he doesn't mean to hurt you, he might get scared and kick out, not knowing you are there, or thinking you are something else.
no because otherwise it will buck

no, they do not, horses are the only known animals to sleep standing up.
If you mean love in the since that you like them, then yes it is perfectly Okay.
some horses sleep standing up because it takes a lot of energy to sit down and then get back up.
Yes, horses do lay down to sleep, but it is less common for them to sleep in this position compared to standing up. Horses have a unique ability to sleep both standing up and laying down, and will choose their preferred position based on their level of comfort and sense of security in their environment.
I either box or standing stalls.

Yes, most horses sleep standing up but sometimes they do lie down.
They're standing back to back.
Standing up sometimes laying down
Yes, horses usually sleep standing, or at least they rest. Because they are prey animals, they've adapted to standing while resting so they can bolt if a predator is near. They also sleep while standing because of their weight; horses are big enough to actually crush their internal organs and structures if they lay down for several hours at a time, which can lead to death.
Yes, horses can sleep standing up due to a "stay apparatus" in their legs that allows them to lock their joints to remain upright. They do lie down for deeper sleep, but can nap while standing to quickly rest.
