What is a post hypnotic suggestion?
It is a suggestion given to a subject in the hypnotic state that is to be carried out minutes, hours, days, weeks, months, even years later in the waking state. The purpose of the post hypnotic suggestion is to help the subject change his habits and attitudes. For example, if a subject has an irrational fear of entering an elevator, he could be given a post hypnotic suggestion that the next time he has to use an elevator, he can enter it and experience the same pleasant sensation he is aware of upon entering his home.
