Again, such suggestions may be for a future time, and be performed only when a suggested interval has elapsed; they are then called Deferred or Post-hypnotic Suggestions.

Post-hypnotic Suggestions are those which include the command not to perform them until a certain time after the subject has returned to his normal condition; such suggestions--if of reasonably trifling character--are actually carried out afterward in the normal state, although the person is conscious of no reason why he should act in such a way, having no remembrance whatever that he has received the suggestion when hypnotized.

Such post-hypnotic performances may be deferred by suggestion for many months.
