What does dreaming about door mean in the Bible?

Doors in Scripture are moments of decision: Jesus stands at the door and knocks, calls Himself the door of the sheep, and Paul speaks of a great door for effective work opening before him. A door in a dream — open, closed, or locked — often marks a threshold God is setting before you. In the SoulGuide Dream Guide, door is filed under places — one of 54 symbols in the guide — and is answered with 3 King James Version passages quoted in full: Revelation 3:20, John 10:9, 1 Corinthians 16:9. Each passage below carries a short note explaining why it applies to door, so the entry can be read on its own without the rest of the guide.

“Behold, I stand at the door, and knock: if any man hear my voice, and open the door, I will come in to him, and will sup with him, and he with me.”

“I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.”

“For a great door and effectual is opened unto me, and there are many adversaries.”
