Yes, it's a projection of fantasies, however your conclusion in unnecessarily pessimistic. It could be that these fantasies come from mass media.

When we know nothing about a topic (UNKNOWN), anything stated about it in the positive seems plausible -> Art creators play with the UNKNOWN (supernatural, aliens, <insert any person/place/thing that we know little-to-nothing about>) to add plausibility -> The content of that medium becomes the first contact with the UNKNOWN for many people -> When the UNKNOWN becomes known then people still have the ideas that were propagated -> We get to your comment.

It's not necessarily that people have a world domination complex.
