Oh yes, this has happened to me throughout my life. For the 45 years before I was diagnosed, I would often try to honestly describe my perceptions of the world only for people to assume that I was joking, mocking myself, exaggerating, or high on something. I ended up either resolving to never talk about those things again, or talking in quite a flippant way about them so that, if people thought I was being self-deprecatingly funny, it would seem like a plausible explanation and I could laugh along with them while secretly cringing inside. This was sometimes how I discovered that parts of my mind didn't work like other people's (e.g. hyper-focus, dissociation, sensory sensitivities, synaesthesia.)
