Is being Intuitive sinful?

I'm a very intuitive person I always have been since birth. I pick up other people's emotions to the point crowds can be too overwhelming for me. & if you ask me what time it is I always know without looking. I've had 3 grandparents pass away and each time I would wake up in the night ice cold and can see them standing over me. The first time this happened I was 5. I have never called upon the dead or tried to do anything with this stuff because I know that is witchcraft and a sin to do that but is it already a sin now? I don't know how or why this happens to me but my mom also has experienced a lot of these things and has even had premonitions. Should I just ignore it? Is it the devils temptation?
