I’ve noticed a recurring issue with myself and I want to understand what it is.
In noisy or overstimulating environments (like restaurants or crowded places), I sometimes unintentionally say my thoughts out loud without realizing it. It’s not deliberate — it feels like my internal thoughts (“inner speech”) bypass my usual filter and come out as actual speech.
The strange part is:
- I often don’t notice it in the moment
- Other people hear it before I’m aware I’ve said anything
- It tends to happen more when I’m mentally tired, emotionally uncomfortable, or when there’s a lot of background noise
It’s not constant, and in quiet environments I have normal control over what I say.
It feels less like “talking to myself on purpose” and more like a failure of inhibition — like my brain doesn’t properly stop thoughts from becoming speech under certain conditions.
Has anyone experienced something similar?
Is this related to attention control, executive function, or something like mild disinhibition under cognitive load?
