There are people who have recognised power of visualisation.
I am not trained in these powers. I am no authority to speak on this subject since I have not tried it first by myself.
But what I understand from reading various articles and books is something like this:
1) Imagine and visualise a Stage where a drama is played.
2) Before the show time begins, visualise and PLAY the role which you are supposed to play.
3) The above two things are not possible unless you have:
a) Fixed some time for rehearsal,
b) And you know how to do this.
4) The a Preparation includes Rehearsal. Rehearsal is also a kind of preparation. If preparation helps, rehearsal also helps.
5) Rehearsal should be of such nature that, you get a feeling of Déjà vu when you are passing through this real event in future.
6) For lawyers, it sometimes like, mentally, "Arguing before a Wall", a day before the case is listed for hearing.
7) It is obvious that a person who has done a rehearsal will perform better than what he would have performed without a rehearsal.
8) There is rule: "Isolation and Discipline is essential for progress of a human being." Adherence to this rule is must when you are rehearsing a future event in your mind.
