Depersonalisation?

Yes this is a very common sensation for people that experience high amounts of anxiety, and I used to get really hung up on it whenever it happened to me. My understanding is that when we experience a lot of stress/anxiety, the brain kind of protects itself from overstimulation by shutting down the parts of the brain that are responsible for taking in information from the world, or making sense of things. It does this as a defense mechanism. This is all well-and-good, unless the feeling of being disconnected from everything causes more anxiety for you, in which cause you sort of continue to add fuel to the fire. The more anxious you feel about it, the more depersonalized you will feel! It's a vicious cycle. My best advice when this happens is to recognize it as just that: a defense mechanism. Nothing more, nothing less. You can even try to be thankful for it. Smile about it, because it's something that has helped us cope and survive for hundreds of thousands of years as a species. An analogy I like to use is someone giving you a sweater as a gift. Even if you don't need it at all (or think it's really ugly), you can still smile and appreciate the fact that the person giving you the gift cares about you. So it's pretty much like everything else anxiety/OCD related. Your goal isn't to "get rid" of it, so much as to acknowledge it for what it is. If you train yourself to do that, it won't last nearly as long as it usually does, and happen much less frequently. That's been my experience, at least.

Yes, I remember experiencing this with my HOCD during quarantine. Let me tell you that it felt weird, almost like if nothing is real. Im unsure how to get out of it since, again, it was during quarantine.

Remember that it’s just your brain trying to protect you. I know how hard it is to do but please try to not be afraid of it.. it’ll only make it last longer as it’s supposed to protect you when your brain perceives threat.

I think the big help for me was realizing how scary it may feel it 1000% can not hurt you and is a symptom of really heightened anxiety, after I came to grips with that it never bothered me, it always passed and couldn’t tell you the last time I’ve ever even had it.

What is it ?

I've had this experience! It feels like nothing is real, like a dream

I experienced meditation induced depersonalization/derealization intermittently from 2014 - 2021. The longest instance was approx 2 months following a 7 day meditation retreat. I stopped meditating in Jan of 2021 and the instances went away completely until I decided to test the waters and tried a one day retreat this past Dec which brought it back but only stuck around for a little over a week. What really helped was simply not checking to see if I still felt or noticed it. That only perpetuated the symptoms.
