I think in this context Illusion might be interpreted as follows:
We are hardwired, or very strongly conditioned by experience, to assume certain observations can only result from certain specific implied attributes of what is bing observed. But these implied attributes may not be there, and observation is actually generated through some exotic, hitherto unfamiliar manner. In this case, implied attribute is an illusion.
