this depends on what your definition is of a 'long time'. Horses must sleep laying down to get full REM sleep, but this only lasts for a few minutes. Some horses also like to lay on their sides in the sun to rest. However if a horse has been down for an hour or more, or is extremely still while laying down it would be best to check the horse and call a equine veterinarian.
A horse needs to belive in you. If you first see a horse he or she won't listen to you the first time. It takes a quite long time for a horse to listen to you and do what you say.

This can take a long time if the horse is water shy. Start with a little bit of water and work into what you want it to finish in.Start out slowly, spend a lot of time on it and move to a larger portion of water when the horse goes into smaller portion of water with ease. This will take patience and a long time but if you stay with it, your horse will come to trust you and will go anywhere with you.
That is unknown, since it was a long time ago.
