The Rubber Hand Illusion
If you happen to have a realistic looking rubber arm in the closet , then this hallucination is for you. Begin by hiding your actual arm behind a box on a table so that you can't see it. Then arrange the fake arm on the table, so that from your point of view it looks like it could be your hidden arm.
A friend should then stroke both the real hand and the rubber hand in the same place and at the same time. After a few minutes, you should feel like the fake limb has become your own flesh.
Then have your friend stab the rubber hand, or hit it with a hammer: You will feel a powerful jolt of anxiety and pain, since your brain is convinced that the rubber hand is real.
