I stick to door teleports now. You can always see if its worked before you step through.

I think "out of bounds" is a good description of it. Your brain must be putting a lot of work into creating these realities. If you surprise it, it defaults.

James is right. I think its important to visualise where you want to end up.
This gives you mind a chance to anticipate and create.
