Horses can get fleas
When my neighbor moved to Florida, she had her horses in a sand lot.

My horses were in sand the five years we lived in SoCal's Low Desert area and never had that sort of issue, so I think sand fleas may be a territorial thing.
Aren't they cute - not. Sand Fleas
It's possible what the OP is describing could be sand fleas but, I am on the "it's lice" side of the fence
Sounds like vet time to me since lice will spread.
Blankets, saddle pads, brushes, etc. need to be kept sterile and not shared with any other horse. I wouldn't even brush another horse after brushing this one until I found out what the critters are.
