It might have been a matter of belief. You weren't sure and you tried. The doubt was stronger than the will.
The verb "try" includes the presupposition of possible failure.
When in a lucid dream you try to go through solid objects, like walls, sometimes you can't for the same reason.
Everything expressed here is what I believe. Keep that in mind when you read my post, as I kept it in mind when I wrote it. I don't parrot others. Most of my spiritual beliefs come from direct channeling guidance. I have no interest in arguing whose belief is right, and whose is wrong. I'm here just to express my opinions, and read about others'.
