StopAbductions.com has a guide to building your own “Thought Screen Helmet”. From the website:
The thought screen helmet blocks telepathic communication between aliens and humans. Aliens cannot immobilize people wearing thought screens nor can they control their minds or communicate with them using their telepathy. When aliens can’t communicate or control humans, they do not take them.
The thought screen helmet has effectively stopped several types of aliens from abducting or controlling humans. Only two failures were reported since 1998.
Go read it. It’s funny.
