Will I Be Able To Do Things I Normally Cannot?

Unfortunately not, at least when it comes to physical talent.  You might be less inhibited, but if you cannot play the violin, or moonwalk, then when hypnotised you will still be unable to do those things.  However under hypnosis you might believe that you can, which is the basis for many excellent gags.

You may be more agile or stronger however, and there is plenty of evidence to show that hypnosis allows you more or better physical control.

An interesting effect does occur where you are an amateur at something, and held back by self doubt and internal criticism.  Under these circumstances you may find that in trance you are a much better performer than when fully conscious, because you are no longer getting in the way of your own talent.  Public speaking anyone?
