You notice something.. unusual. A strange.. insect like creature that has hyper-reflexes and hyper movement. It moves faster than the human eye, and it times its movements to electrical impulses in the brains of nearby beings. It uses this technique to hide, either by hiding behind the head of a person looking for it or by hiding in their scotomas (blind spots) and saccades (clipping during eye movement). It seems to just be hiding out of your line of sight, but you are able to catch glimpses of it if you move fast enough. What do you do?
