If you have dreamed of getting a knife in your arm in a dream: If the words that come out of your mouth do not match with what you do, it may cause problems. Someone who cannot attract you or gets angry with you by misunderstanding some of your attitudes may cause confusion. To have a knife in your arm in your dream indicates that you will gain power or property, follow the good ones, and attract a lot of evil eye with the increase in wealth. If you have a knife in your arm in a dream and you don't get hurt, it means being prepared for the hereafter and improving yourself in religious matters.
