I think a lot is a bastardization or 'chinese whisper' effect on snippets of 'truth' that the JWs are taught, which they expand and attempt to apply in a practical way....
Which is intersting, because, from a JW view point, that in itself can be a danger

“Meditating on the fact that the angels are with us in the ministry is a source of encouragement to me,” says Anna. “I value the help they provide under the oversight of Jehovah and Jesus.” What a privilege it is to be able to work with the faithful angels!

Angels follow sisters when they are out in service. If angels weren't following them, sisters would be getting raped everyday.
Which can be dangerous as JW sisters feel more relaxed to 'take risks' that they shouldn't

Questions From Readers: Can Satan and his demons read our minds?
There is nothing in the Scriptures to indicate that Satan and his demons can read our minds or thoughts. Rather, the implication of the Scriptures is that only God can read the mind of man: “Mere man sees what appears to the eyes; but as for Jehovah, he sees what the heart is.” Further we are told regarding God: “There is not a creation that is not manifest to his sight, but all things are naked and openly exposed to the eyes of him with whom we have an accounting.”—1 Sam. 16:7; Heb. 4:13.
However, most likely the demons can, because of higher intelligence and better powers of observation, note what is in the mind of man because of his actions and facial expressions. Thus when a man goes contrary to Matthew 5:28 it may be apparent on his face, and so one could tell what is in his mind even though being unable to read it. So they may take advantage of weaknesses that one makes evident and tempt him to sin.
This underscores the importance of right thinking and dependence upon Jehovah. When wrong thoughts enter the mind they should be rejected at once; they should not be entertained, opening the way to sin. (Jas. 1:14, 15) Rather, draw close to God through prayer and meditation on his Word, because in this will be found protection against wrong desires and against the temptations of the Devil and his demons.—Jas. 4:7, 8; Phil. 4:8, 9.

Don't say your fears out loud because satan can hear you if you speak them out loud and he will use them to harm you.
Which can be dangerous from a JW perspective, because they believe the demons have higher intelligence and better powers of observation.
