I believe "practicing in your head" is actually called previsualization and is a well known and effective way to create memory engrams which then translate to physical expertise.
Meditation is something else. There are many types of meditation, but all that I know of involve "not-thinking" (at least at the lower levels) or concentrating on a specific thing like a mantra and/or physical sensation. It too can be an effective aid to climbing by developing concentration and a way to deal with your feeling.
