If we are insecure about how to discern the spirits in certain cases, A.W. Tozer offers a very helpful method to try any new experience, doctrine, or religious movement regarding their effects on our relationship with (1) God, (2) Jesus Christ, (3) the Bible, (4) our (old) self, (5) other believers who are indwelt by Christ’s Spirit, (6) the world and its desires, and as to (7) sin. It is a quite long article of which I only pasted some excerpts on here although the text is pretty long, still. If you want to read more, please, follow the link below. It is well worth reading, I believe. I also think we can use this method in order to judge the origin of our thoughts, our (day)dreams and visions, even everyday occurrences and their effect on us. May God help us sharpen our discerners with what Tozer, who in my opinion had been inspired by God, wrote about.
