Excercises for more vivid mental visualizations -

How many of you fellas visualize consistantly, to help you improve in your craft? For you fellas that visualize, I came across an issue of having shallow visualizations recently. Example:

Recently, I imagine fighting someone that I will fight, and can only play out a narrow set of scenarios. Also I don't feel in sync with the visualization that I am doing... anyway I lost that fight.

But it makes me think about my experience visualizing from a couple years back - I was going to fight someone, and in my visualizations I would feel all the particular muscles I use when I throw a punch, and I would the heavy breathing that accompaies fight-or-flight response

The issue is that I am not engaging deeply with my imagination - here is some stuff I have been looking into, and it may help you too:
