I was told by a palm reader who was right about everything else that I would devlope my "powers" by 35 but I am not so sure, I have no special powers that I know of. My grandmother I am told was a white witch but I did not know her. I am a normal religious person and have many questions about all of this.

The Bible says our powers are discerning of spirits, prophecying and some other things.
It is important that when you 'develop your powers' that they are of God and not evil spirits trying to deceive.
