Is it normal i hear voices that help me?

I hear voices that tell me things that I have no way of knowing but always turn out to be true. You could just say I'm crazy, but I did some research on schizophrenia and I don't have any of the other signs like hallucinations and I don't hear the voices all the time. They don't say random things or mention everything, they only occasionally tell me things that help.

Once I was shopping for dog food and when I was reaching for a bag of the brand I usually get, a voice said don't buy that. So I got a different brand. I found out a couple days later that the brand I almost bought was being recalled because something in it was making dogs sick. Another time, I was talking to my girlfriend at the time and she told me she loved me. A voice told me she was lying. So I did some snooping on her over the next couple days and sure enough, I found out she had been seeing another guy everyday for over a week.

Sometimes it helps me on huge things too. Once I was out shopping, and a voice told me to leave and drive home right now. I left my cart and got home as fast as I can, and when I did I saw the door wide open. I called the police and they found a guy going through my closet. One of the cops said I had really lucky timing getting home, because the guy said he had only been in my house for a couple minutes, which was about the time it took the cops to get there. There is no explanation for how I knew I should be there. There's other times of course, but this post would be too long if I talked about all of them and you get the point by now.

I don't know why this happens. I don't want to tell anyone because I don't want anyone to think I'm crazy. No one thinks I act crazy and the voices have only helped. I think they have to be something more, but I don't know what. I don't really believe in psychic powers or spirits, but I don't know what can explain it.
