While excellent advice is being offered, it must be remembered that hypnosis is NOT mediumship and vice versa.  Using such techniques does not get you in a place where you are taking charge of the whole attunement process with spirit and your own guides.  Our minds have many facets and mediumship uses one while hypnosis uses another.

Self hypnosis is exactly the same as deep relaxation, an altered state! You are still completely in charge of your mind and faculties as you are with meditation and WILL get you to exactly the same place.....

I never suggested hypnosis was a form of mediumship, just a state of relaxtionat and altered state, are you feeling a bit threatened here....

Again in find you using the inappropriate word 'attunement' as if someone else is going to do something like attune you to Reiki which is nonesense

This is a course in good mediumship techniques and abilities.  I have posted the material and have every right to post as I see fit.  I would suggest, strongly, you find somewhere else to challenge and abuse the teacher.  This is a site for my work, not yours.  

Hypnosis is NOT a good practice for gaining knowledge and input from spirit through meditation.  It is a relaxation technique that takes the mind into places that attunement processes do not.  If you do not understand, read up on it, and don't criticize what you have not learned.

Why not perhaps do drawing exercises. Go on courses that stimulate your artistic perception. Learning to paint and draw by using your imagination will help. Your husband could give you an idea to draw or paint and by practicing this over and over the part of your brain that good at visualising will get better. I have a brillinat ability to visualise. I have always had because when I was small I was so in pretending I was some singer or action hero to a point of being lost in that imagination. I could do that for hours, he he. I think though as a consquence it has left me with an ability that if I want to let a spirit play with my imagination so that spirit can get things across he or she can do it very well. Yes definity art lessons are the key.

I've noticed in my expierence that not everyboy "sees" the same way.  

I would visualize a place, the way it made me feel, the time of day, as if looking at an old photo book.
My friend would not pick up the picture, but the feelings.  I had yet another friend who would only see color.

You must first determine how you "see" and work with that.  Little by little you can open up more and "see" other ways.  

Picture how a sunset (of any other image, this is just the first one that came to my mind) makes you feel, immerse yourself in that feeling until you feel you are actually looking at one.  Slowly add in a few colors that a sunset would have.  Soft reds dancing in your mind.  They may seem faded or bright, the important thing is that you are taking it step by step and not expecting to just be able to do it now.  As the saying goes, practice makes perfect.  As you add in more colors, start to control where they go, and their shape.  See if you can make those colors look like a makeshift sunset.  

I've also noticed that not everybody associates the same feelings with certain colors, so it is up to you to determine what the colors mean to you

I hope that helps a bit
