Isness? Is It a Property of Experience?

Isness is almost like a quality or a property of experience, which is the being property. But no, I don't think it's quite right to say that isness or being is a property of experiences. Experience would have to be present first and being would have been one of its temporary finite properties. The screen is not a property of the movie. This may be not a very helpful question at this point. Sorry.
