Best tip I can give for this. Put your emotions into it. Get immersed into it. If you are visualising getting stabbed or anything(jsut an example)feel the wound and the emotion of whats racing through your mind as you are having a metal blade inserted into your flesh. Girby out. 
Listen to Noodle, he knows what he’s on about.
I believe I read something similar in my coursework about the same areas of the brain becoming activated.
Personally, I read a lot - particularly sci-fi and fantasy, and I have found that over the years this has had a tremendous impact on the quality of both my dreams and my ability to visualise. My advice would be to pick up a good book which demands the use of imagination (fantasy are great for this), and watch your visualisation skills skyrocket.
Interestingly, if I read sci-fi or fantasy while I’m on a caffeine high, my visualisation skills are incredibly acute - I’d say almost waking lucidity (Waking lucidity, eh Noodle? 
). I can literally see the images in my imagination overlapping wherever I happen to be looking - but I guess this is kind of drug induced, even if it’s only caffeine.
I personally am new to Lucid Dreaming, and I have just started working towards those types of dreams. With that aside, I would say that if your reading something and the image comes to you, then run different thoughts through your mind as if they are being read to you or if you were reading them. Then that way you’re telling yourself what the object should look like. If you’re using your imagination to visualise something, then let your imagination run wild and say the apple should be green with purple dots and it should smell like cinnamon . Not necessarily an apple, but you know exactly what you want it to look like. I may not be right in thinking this, but it may work .
I merged your topic with this thread in which there were recent posts about visualization so that you can find some techniques.
my visualization skills are very poor and i would like to improve them. i would like to use visualization to help me concentrate during a WILD (like a spinning cube or something…at least until i get HI) or to help me perform a VILD. are there some exercises i can do to improve my visualization? techniques? anything?
thanks for the help

Hi eyegug,
You’ll find some techniques in the thread I merged yours into. You can also search for visualization on the forum (yellow button on the top of the page). There is also another running thread about Visualisation aid.
And if you want to train your visualization skills there is a Visualization training game in the Playground too. 
I can’t help you because visualization is not my strong point, but I hope some pros will give you some advices.
thanks for merging it and helping me out Basilus West, ill see how it goes!
strange how some people end up thinking about visualization, its not where you can actually see the object infront of you (that would be a hallucination) its thinking about it and forming it in your “mind’s eye”. visualization is used to convince your subconsious into believing something, some people dont understand this they believe that it is simply to keep your mind busy (which does happen and helps for falling asleep but isnt the actual reason for it).
the subconsious has no analytical reasoning and accepts what it is told, it understands pictures and feelings beter than words (which is why you want to incorporate all your senses into it if possible, some emotions also help).
visualization is mainly to make you SC to believe something because even if consiously doubt something but you SC does believe it then you SC overrides it. for example: i once tried a neat self hypnosis tape a few years ago before i got into LDing, while using they tape i began telling myself that i couldnt move my left arm, it was to heavy and stiff, and limp. i then tried to move my arm and i knew that there was nothing stopping it from moving but i was unable to, i tried as hard as i could and even used my other arm to throw it around but was unable to even twitch a finger. i ended up having to wait until the thirty minute tape ended before being brought out and having the effects removed.
Ignorance, don’t you confuse visualization and autosuggestion? I’m not sure I understand your words and your example. 
right well i was tired when i wrote that so i didnt realy explain things to well, but the example is refering to the fact that if you convince you SC something then it doesnt matter if you consiously disbelieve it.
maybe i should remove the example since it doesnt really refer to the rest of the post (i added it because people think you have to absolutely believe that your are going to become lucid in order for it to happen, and thats not true)
Thank you for this explanation. But then I still don’t understand what convincing yourself has to do with visualization. I wouldn’t have thought they were related. Could you explain your idea?
visualization is a method of convincing your SC of something. as you may or may not know, the SC understands pictures, ideas, and feelings beter than words; so imagining (or visualizing) something is a more effective way of telling your SC something than simply thinking about it.
i sort of danced around your question but i guess im just trying to say that visualization is related to convincing yourself because they are the same thing, visualization is just one way to do it.
LaBerge’s Visualization Exercise
[spoiler]EXERCISE: VISUALIZATION TRAINING
Practice Part A once or twice a day for two or three days. Each session need not be longer than five minutes. Then move on to Part B.
PART A
- Sit facing a simple object
Choose an object to gaze at, such as an apple, a rock, a candle, or a coffee cup. Choose something small, sim-ple, and stationary. Put it a few feet away from you and sit comfortably. - Concentrate on looking at the object
With your eyes open, try to encompass the entire object with your vision. Try to soak in an overall visual im-pression, rather than concentrating on any specific feature of the object. Acknowledge distracting thoughts and perceptions and then just let them float away. - Close your eyes and observe the afterimage of the object
After a few minutes, close your eyes and watch the af-terimage of the object until it fades. Then open your eyes and look intently at the object again. Repeat this several times; the afterimage should become more clear, vivid, and crisp each time. Don’t strain to create the image. Let the clarity emerge as if of its own will.
PART B
- Warm up by concentrating on an object in front of you
Warm up by repeating Part A several times. - Visualize the object hanging in space in front of you
With your eyes open, move your gaze away from the ob-ject and try to picture it directly in front of you, several feet away, floating at eye level. It might seem strange at first, but don’t strain. Simply try to let the outlines of the image emerge in space. You might want to start by concentrating on the way you feel about the object rather than its detailed struc-ture. Just accept that the object occupies the space where you are gazing, and pay attention to that feeling—that the image occupies the space because you intend it to. The sense of seeing an image will emerge from that awareness and feeling. - Visualize the object inside of you
When you can visualize the object in front of you, then repeat Step 2, except this time visualize it inside your body. Since some of the lucid dream induction techniques require visualizations of objects in the throat area, try to see the object in your throat. Then move it out again. Shift your visualization from external to internal positions again and again, until it is effortless.[/spoiler]
Can someone explain me this part? I don’t think I get it.
