I figured out a good way to BRB without getting bothered!
You know those patches of grass that come up to a Stag's knees/belly? The ones that look like wheat (They appear a lot near the Playground)? Well, if there's a LOT of it in either direction, you can run there and sit down; Once you do that, only your antlers and your Picto show up. Once you fall asleep, your picto is camoflauged and only the tip of ONE antler show up, so basically, nobody can see you unless you tell someone or stand up.
I've found out this helps with adults and fawns alike, especially when you don't want others bothering you/You don't want spells cast on you. This keeps you hidden from those people who just run up to random sleepers and cast a spell, then run off. So keep your pelts safe- Sleep in the grass! XD
