Cheap and easy. A make-it-yourself shield that will stop the aliens from controlling your mind, and (allegedly) if they can't control your mind they won't abduct you.

And so chic!
But remember:
Keep the thought screen helmet in the safest possible place when you are not wearing it. In Kentucky, one thought screen helmet was taken from a box that was in a closet. The abductee had dental work and could not wear it. She thought she put the helmet in a safe place. Additionally, four other thought screen helmets were taken by aliens when they were not being worn, two in Virginia, one in upper New York state, and one in Brisbane, Australia.
