I think what happens is that people are exposed to reading about, watching stories on TV about aliens and what they might look like and store it in their minds and have dreams that are very vivid that scare them and these dreams happen in a state of normal paralysis during sleep cycles and these people think of that as being captured and held down. I think that some people who are also artistically inclined can dream in vivid colors and the dreams are so real these individuals begin to believe they are really experiencing these dreams in real life. I have had these dreams myself and it always amazed me how my mind could create an imaginary situation with such detail including sounds and smells. However, it's only a DREAM, not real.

The human brain is truely amazing and has the ability to come up with so many amazing creations, this is shown in all the amazing things we have created thoughout our human history. These talents have always astounded human beings so surely this must be something that comes from outside us, a god of somekind. And why would we think that? It's because we are born like all mammels to look for the parent to show and guide us so we learn how to survive. We are also born maleable in that we need to group together to survive and thrive so we tend to have a strong desire to be part of.

While human beings are so incredibly intelligent and creative, they are also predatory. This also is expressed in our dreams, minds, imaginations and actions. The monsters, aliens and ghosts are in ourselves.
