Wearing a mask and costumes for Halloween has made it a fun ritual to participate in.
 

A few years back there was the television show, Beauty and the Beast, with Ron Perlman (The Beast), Roy Dotrice and Linda Hamilton? The Beast's favorite day of the year was Halloween when he is able to walk around, as himself without being afraid of any repercussions to his beast-like appearance.

He even gets complimented for his "cool costume."

Yes, Halloween is a time when you can pretend to be someone else even if it is yourself.  It is a time when you can bring out the inhibitions that you've been hiding all year around and dress up as your alter-ego if you like.

Most of us, in one way or another, put up mental masks all year long. Some call it "walls." These walls hide the part of us that we don't want others to see.

 
Why not use the Halloween masks that best represents what you would like to visualize and manifest. This way, for one day, at least, you can walk the walk and be what you desire to be.

For example:

You want a vacation.
Dress up as a tourist would to wherever it is you want to travel to.

You want a motorcycle.
Dress as you would when you do get that motorcycle.
 

You get the picture.

In the context of mind control, the more accurately and clearly that you can visualize your goal, the more real your goal becomes in your mind and you will manifest what you envision as you envision it to be. 

Have someone take a picture of you in your Halloween costume, so you can put it up on your vision board to be reminded of it for the rest of  the year or until you manifest your desired outcome. Here is a good site to go to if you want to learn more about visualization techniques.
