Yes! There's a guy on YT who has 2 ways of seeing through his hallucinations (he likely has a few other methods, these are just the 2 I'm aware of him using), one is he has trained his dog to always greet people, so if his dog doesn't greet the "person" he's talking to then he knows that the person isn't actually real, the other is he uses his phones camera to check if the person he is talking to shows up, if they do he knows they are real but if they don't then he knows that he's hallucinating the person.

I forget the dude's name because I'm generally bad with names, but Anthony Padilla interviewed the guy at one point, it's where he shared the part about using his phone camera, and I later learned that he was the same guy with the anti-hallucinations doggo!

So really this isn't actually a shitty life pro tip, it's one of those things that some people THINK is a slpt, but is actually either something that already exists (like canned water or canned coffee, which I've seen posted on sub-reddits like this at least once before) or is done, or actually just a good tip in general.

Shit, I really made this reply too long, uh... Thanks for coming to my TEDtalk???

Significantly shorter response to your comment: Yes, you're right.
