Yes I agree, the more manic you are the more likely you are to intepret things in a none rational way. Check your meds to make sure that they do not cause these side effects. Call your doctor immediately because this is a sign of escallating mania.
Having said that, if everything checks out and you are doing ok, start keeping a journal of events. If other people are really seeing things also, get a camcorder and keep it handy to see if you can catch something on camera for documentation.
However, whenever I have been at my most manic, I always saw things in my sleep and totally awake. If you are adding drugs or alcohol to the mix, wow that will really put some hallucinations in your day.
