One point from the post is that Satan's main tool to use against us and blind us from God's light is the creation itself. This is a really important principle. Satan's darkness is described as a veil and a chain in the same verse (see Moses 7:26). It simultaneously blinds us and takes us captive.
Those experiencing this fear draw closer to the creation -- in some cases they fall to the earth. In other cases they attempt to hide in the earth (or wish they could).
Below, I'll list the many examples I found of fear and darkness.
Fear of Judgement
10 O ye wicked ones, enter into the rock, and thee in the dust, for the fear of the Lord and the glory of his majesty shall smite thee. ...19 And they shall go into the holes of the rocks, and into the caves of the earth, for the fear of the Lord shall come upon them and the of his majesty shall smite them, when he ariseth to shake terribly the earth. ...21 To go into the clefts of the rocks, and into the tops of the ragged rocks, for the fear of the Lord shall come upon them and the majesty of his glory shall smite them, when he ariseth to shake terribly the earth. (2 Nephi 12/Isaiah 2)
11 And they that will harden their hearts, to them is given the lesser of the word until they concerning his mysteries; and then they are taken captive by the devil, and led by his will down to destruction. Now this is what is meant by the of . ...14 For our will condemn us, yea, all our works will condemn us; we shall not be found spotless; and our thoughts will also condemn us; and in this awful state we shall not dare to look up to our God; and we would fain be glad if we could command the rocks and the to fall upon us to us from his presence. (Alma 12)
Fear prior to a marvelous conversion/revelation

And the was taken from off the eyes of the brother of Jared, and he saw the finger of the Lord; and it was as the finger of a man, like unto flesh and blood; and the brother of Jared before the Lord, for he was struck with .
7 And the Lord saw that the brother of Jared had fallen to the earth; and the Lord said unto him: Arise, why hast thou fallen?

42 And now, when he had said this, he unto the earth, if he were dead.

(3 Nephi 8)
11 And as I said unto you, as they were going about against God, behold, the of the Lord unto them; and he descended as it were in a ; and he spake as it were with a voice of thunder, which caused the earth to shake upon which they stood;
