Intuition, Deja-vu And The Weather

I believe I have these psychic abilities, but in a way am to afraid to look into them, because of religious reasons and the fact that people don't believe me.

I have a very good intuition, I can usually decipher what its trying to tell me and 99.9% of the time it is correct. I get this strange feeling when something bad is about to happen, I just feel strange, its like a flow of bad energy goes through me. The odd thing is that my intuition only seems to work for bad things. Usually they are only relevant to me and my life, but sometimes when I concentrate enough, I feel the same feelings about my sister's life. She is actually the only person I tried to concentrate on. I guess I don't know the extend of my abilities because I have never concentrated hard enough or practiced for long enough. I'm not quiet sure how I would go about it? I have tr I have done meditation, it did make me feel light but these days I am unable to find quietness inside my house as we have gotten a small dog.

Also, I am constantly getting feelings of deja-vu, I remember the first time I had deja-vu was when I was 12, I was playing in the court yard with some friends and one of the girls said something that trigered the feeling of dejavu and for the next 10 minutes everything that was happening just felt strange, as if I knew it was coming but couldn't put my finger on it. (I guess that's deja-vu)

I can predict the weather. I do not practice this too often but everytime I do predict it, it freaks my friends out. It will be a sunny cloudless day, and I just know that it will rain later. Most of the time, people do not believe me but it just happens. I can't explain how I know, I just get this strange feeling and I know it will rain later on today. I have managed to predict the time it will happen, but I'm usually off 5 minutes or so.

I have also used a crystal pendant and have successfully spoken to the other side, mainly my grandmother who she says is my guardian. After speaking to her, I asked her advice on numerous things, and all of her answers came true. She said that even though I could, I wouldn't get back together with my ex boyfriend at the time. (He broke things off with me) Funnily enough, that's exactly what happened.

I know that if I put my mind to it and concentrate, I should be able to work on these skills, but it just doesn't appear to be working for me. Does anyone have any suggestions on what I should do?

I don't know if my "abilities" are real, as I said, I am taught in my religion not to believe that humans have any special powers, but I know this is real. Do you think what I have are psychic abilities?

Thank you.
