The Austrian medium Rudi Schneider was investigated in 1924 by the physicists Stefan Meyer and Karl Przibram. They caught Rudi freeing his arm in a series of séances. Rudi claimed he could levitate objects but according to Harry Price a photograph taken on April 28, 1932 showed that Rudi had managed to free his arm to move a handkerchief from the table. According to Warren Jay Vinton, Schneider was an expert at freeing himself from control in the séance room. Oliver Gatty and Theodore Besterman who tested Schneider concluded that in their tests there was "no good evidence that Rudi Schneider possesses supernormal powers."
You can cleanse your home of negative energy with sage or sweet grass. You can also perform a smudging ceremony, although this is best done by respectfully approaching a spiritual First Nations person. You can also perform a salt ceremony to protect your home. Lastly, you'd want to meditate regularly, psychically surround yourself in white light, and tell any negative energy that it does not have your permission to interfere with your life.
