definately they do, remember watching my mare on foal watch last year and she even winnied in her dreams soooo cute, not sure what she was dreaming off but the winnie was really muffeld, the others also regularly 'canter' in their dreams in the field - really funny to watch
They can fool you though - Dex knew I was there and the dog was running around him - think he was worried I might be going to ask him to do something so was "fake" sleeping
Yes, of course they do loved looking at all your sleeping ponies
Normally mine is fine with being sprayed with fly repelent, last night... Lots of noise from his stable... Just took me half an hour to catch and spray
Definitely. One of mine twitches their hooves but I've never heard him whinney. I've never seen the other 2 dreaming but I'm sure they do. Unfortunately, I've never been able to get a picture or video - really wish I had.
I even woke up the horses in the paddock next to mine just to check. They were lying parallel in a row. I did wake them up slowly by saying 'are you alright'. The first mare sat up and glared at me.
