This is a constant thing for me.
I try to take the feeling I have my in my dreams and replicate them on the ice; Sometimes It works and sometimes it doesnt
Honestly, I do think it that dreaming about skating does make a differences. I think it works a bit like your subconcious is thinking about what you are suppose to be doing and then transferring it into your muscles memory.
A few weeks ago I started thinking and also dreaming about what a tight and stable air position was like and out of the blue, my ankles are constantly crossed, my arms tucked in over my right side and a strong back. My coach actually complimented on the fact that all my jumps are looking prettier and more stable now.
