Hi!
And yep, that's the trick, make your mind believe in what you're doing. For example with that teleportation, before you walk through a wall, say out loud what your destination will be and truly believe you'll arrive there once you've walked through the wall. It's all about tricking the mind.
Splodeymissile also really explained the Freud-theory I was talking about :p So his explanation might help you in ignoring that sex-drive, should you want to, and choose a different topic.
