Tying hypno triggers on possible everyday things like those, like a scalp massager, fun to tinker with and try out -w-, especially fun when someone else uses it on you, just plop it on someone's head, slowly slide it down, then watch as their eyes rollback and they shiver in delight, the nice delightful feeling it gives when trying it for the first time is definitely gonna give a potent nice shock to the senses, that it could possibly used as a funny silly hypno trigger tbh
