No, sorry, I can't be more specific as I've never heard of anything like this before and I'm not an expert or a professional. It just sounds more like dissociation to me than psychosis (both involve a detachment from reality, but with psychosis it becomes difficult to tell what is real and what is not real). I once dissociated during an apointment and I saw everything in black and white for like half a minute, then it passed. I felt confused and also felt like I was in a movie rather than in real life, but I was still rational (no delusions or loss of reality) and knew the world wasn't really black and white or a movie. Other times I've had the feeling that I'm not real, but it wasn't psychosis because it was just a feeling - I was still rational. Dissociation (and psychosis) causes and can be caused by stress, which I guess could explain the difficulties you had with processing sensory information, though I'm not exactly sure that I know what you mean. But I do know that when I get stressed, thinking straight and understanding information becomes very difficult.

If you have been psychotic before and this recent experience troubles you then it's probably a good idea to talk to a professional no matter what it actually is. And no one here can give you a definitive answer, but a professional might be able to.
