Welcome to the forums! That seems like a good idea because it keeps you awake, concentrated on a question while still getting relaxed. However this method was posted a short time ago in the Astral Conciousness forum as the Koans or I believe Kog-ans as one replier called it. Also I can give you the answeer to the tree in the woods question[
]. It wouldn't make a noise because unless someone or something is around to inerpret it as a noise it is merely a vibration in the air.
