Idea 2 for Psychological Horror

We have thought about other ideas we could use for our teaser trailer as we cannot decide what to include. Lewis had an idea which used a blinking effect, that you were looking though someones eyes and seeing what was happening and when they blink the scene changes, We looked on adobe premiere elements which is what we will use to edit our teaser trailer and there was no special effect that we could use to create it. His idea involved a character male or female was doing every day activites like working and being at home but when he blinked he could see a shadowed figure in a dark field, he blinked again and was back to normal day life, but when he blinked after that the shadowed figure was closer. This is a rough idea of what we could do.
