Can you Verify those feelings though? That's the danger with channelers if you have no way of knowing the persons feelings, especially if they keep to themselves.
This can apply to any reading with any reader. However, to answer your question there are two ways
1)Do their actions match their words? if the reader is telling you that so and so loves you and wants commitment and that person doesn't follow through, then the reader is either full of it or channeled the wrong person. Actions always speak louder than words. Always.
2)Ask the person.
For me, she stressed that the POI had to 'clear things out' multiply times hence the distance and I can attest to this that it is true. He also said it has nothing to do with me and everything to do with him and this is also true. Funnily enough I read with a psychic on cp.com. He said when the POI contacts me he will mention things about "clearing out work issues/people issues." Literally what Judi told me minus the work and people issues.
Also with any reading you just have to use your common sense and intuition.
