I'm not sure what "questioning your reality" means. Sounds like something you would do on LSD.

Ghostbusters.

As a person who just had psychosis 2 days ago, go to people who understand you and where you feel safe 🥲 Don't call the police because a swat team will arrive 🙈😂 Endure it until you actually are at the safe place 🙈😂

I taste my own pee to make sure it's real.

Improvise. Adapt. Overcome.

Psychedelics

Drugs

Other people, as they have diffrent point of view. Beware that some will try to manipulate you.

A dream check like checking the lights or poking my palm with my finger?

Depending what you actually mean, I think a therapist might be your best bet. Like, are you unsure if what you're seeing and hearing is real or are you just having an existential crisis?

I'm not sure if I quite understand the question, but would introspection be an answer? Otherwise maybe some close friends and family

I don't really have a specific person that I go to, and it doesn't happen that often (at least I can't think of an example)

The Oracle.

Myself. I work out what all the steps were that led me to being right here right now. Like where did I wake up this morning, how did I travel to this location.

I turn to the little pit in my head, shove all that inside the compacter and force it down for a nice good little forever. Does it work? TBD

to authenticate, ask yourself 3 random security questions:

what is your mother's middle name?, which city did you meet your significant other?, what's the name of your favorite teacher?

sites love to do this so it might be working for them~

jokes aside, just focusing and grounding is a good first aid when things spiral out of control.

there's groups out there that like exchanging affirmation cards, if that rocks your boat.

Borderline schizoaffective, psychotic features. Constantly questioning sanity. Reality often surreal. Dbt, cbt has helped the most. If I practice mindfulness, grounding exercises daily.... when mind spirals, reality starts to explode, easier to come back, keeps me tethered.

Tho, once as kid, when I became convinced I might be a disembodied brain floating in a jar, started to seriously freak out. Came home in terrorized panic, flipping madly thru my bookshelf, and reading "summa theologica" finally made the panic stop.

I like to get in touch with just how well my intended body movements are relayed through my senses. It's why I do flow arts and competitive gaming. It reminds me reality is there trading blows with me.

It's never really bothered me too much. Who gives a shit if nothing's real, I'm still experiencing it

Jesus Christ. Just kidding, it's David Rakoff. I find his essays comforting.

Anything with text to see if it's backwards cuz if it is, I'm dreaming.

Karl Marx. Man was ahead of his time. Even made the western hemisphere deem his writings as taboo since they were afraid of his ideas.

Sitting with my dog.

Questioning reality is a fools effort and I've wasted too much of my brain energy in life thinking about it.

That said, I've learned when I start to think about it again, I focus on being present + attentive and that'll gets me back in-line.

Not sure what that question means, but my answer is probably God

I turn to whoever I had been rejecting before. Isn't that the point?
