If you dreamed that your arm was numb: Don't make sudden decisions, you may make an effort to make progress. To see that your arm is numb in your dream indicates that the person who sees the dream works hard, gets sick and goes through a difficult and grueling period, that his business will come to a standstill, and that he is making a loss while trying to make a profit. Seeing that your arm is numb in the dream is interpreted as the sin of many people for their own interests.
