Sometimes real life is FAR more entertaining than the movies.
The first thought screen helmets were made in 1998 and used aluminum foil. They were sent to an investigator in Iowa. The investigator reported that one user tried it for a short time with no results. Afterwards, the investigator could not be reached and the whereabouts of the helmets are unknown.
About 8 thought screens were made in early 1999 using a metalized plastic which is used in static shielding bags. Six users reported success but two users were overcome by telepathic commands from the aliens, removed the helmets and were taken.
From 1999 to 2012 over 110 people abducted by aliens have reported using thought screen helmets and hats made with Velostat. Since 1999 only two abductees were taken when they wore thought screen helmets with Velostat. Most of the other abductees using thought screen helmets reported success. Some abductees could not be reached after they tried their thought screen helmets.
In 2007 several thought screen helmets were made with ten and twelve sheets of Velostat. Although eight sheets of Velostat are adequate telepathic shielding in most cases, some abductees state that they had a headache or felt nauseous with that level of protection. This situation may indicate that the aliens have increased the power of their telepathic transmission, especially when they directly confront their victims, but the signal remains scrambled by the Velostat.
