The scripture clearly instructs us not to have worry and fear of these things...
Case in point - Proverbs 26:2 "An undeserved curse will not settle."
And the clear reference to seeing the angelic realm in 2 Kings 6 and not to be afraid.
15
When the servant of the man of God got up and went out early in the morning, an army with horses and chariots had surrounded the city. So he asked Elisha, “Oh, my master, what are we to do?”
16“Do not be afraid,” Elisha answered, “for those who are with us are more than those who are with them.”
17Then Elisha prayed, “O LORD, please open his eyes that he may see.”
And the LORD opened the eyes of the young man, and he saw that the hills were full of horses and chariots of fire all around Elisha.
So to reject the scriptural reality of these things, because some fear, goes against scripture itself.
