That is SO nice!! Your work on the light and shadow is remarkable, and well as the combination of images and the merging of ideas. Perfect!
I don't know if you'll like this idea or not, but I thought that maybe the dark silhouettes, or perhaps just two of them, could have a "New Agey" feeling about them. For example, maybe one person could be lifting her arms as if she was welcoming the arrival/presence of the hyperdimensional beings. And another one by her side, showing support, or something. IMHO, that would show not only the people who are kept in ignorance just living a normal life, but also those who choose to ignore the signs/are misled to ignore them. That would create a bigger contrast between human beings and the forces "above" them. OSIT. But maybe I misinterpreted the meaning you are trying to convey.
My 2 cents.
