Real practice: Rarely to never
Fake Practice: almost daily.
What I mean by fake practice is attempt to move something in my area by very meek will. The reason I do this isn't because I want to learn how to use PK. It acts as a reality check for lucid dreaming. I do it daily, every so often I do it in a dream, the thing moves, and I go lucid. From there the astral is my playground.
Real PK is something I'm thinking of picking up, which means practice in my near future, if I overcome laziness...
Inception, much?
I don't get to practice that often. I do try to practice when I can though, mostly with microPK dealing with luck/possibilities of things happening.
