Your interpretation is spot-on Sparkle. The dream certainly represents either evil people or evil spirits, probably spirits, who do not want you to prepare teachings for God. They want lies, not the truth. Although evil spirits won’t be able to do to you what this shadow man did to you, the dream certainly reveals how furious they are with you and what they surely would have wanted to do to you if they could.
Of course, the Husband that you are screaming for to help you is your heavenly husband, Jesus Christ. He will be with you always to protect you as He uses you to write and prepare teachings for the body of Christ that He approves of.
